The sole question posed by this appeal is as follows: When the Industrial Commission finds as fact, supported by competent evidence, that a claimant is totally incapacitated for work and 55 percent of that incapacity is caused, accelerated or aggravated by an occupational disease and the remaining 45 percent of that incapacity for work was not caused, accelerated or aggravated by an occupational disease, must the Commission, under the Workers’ Compensation Act of North Carolina, award compensation for 55 percent disability or 100 percent disability? Upon such findings of fact, our Act mandates an award for 55 percent partial disability.
Except as to questions of jurisdiction, the rule is that the findings of fact made by the Commission are conclusive on appeal when supported by competent evidence. This is so even though there is evidence to support a contrary finding of fact. Morrison v. Burlington Industries, 301 N.C. 226, 271 S.E. 2d 364 (1980); Inscoe v. Industries, Inc., 292 N.C. 210, 232 S.E. 2d 449 (1977); Anderson v. Construction Co., 265 N.C. 431, 144 S.E. 2d 272 (1965); Rice v. Chair Co., 238 N.C. 121, 76 S.E. 2d 311 (1953); Henry v. Leather Co., 231 N.C. 477, 57 S.E. 2d 760 (1950). The appellate court does not retry the facts. It merely determines from the proceedings before the Commission whether sufficient competent evidence exists to support its findings of fact. Moses v. Bartholomew, 238 N.C. 714, 78 S.E. 2d 923 (1953).
The evidence in this case, especially the medical evidence, overwhelmingly supports the Industrial Commission’s findings *7that 55 percent of Mrs. Morrison’s inability to work and earn wages is caused by “chronic obstructive lung disease, due in part, to causes and conditions characteristic of and peculiar to her particular . . . employment in the textile industry,” and the remaining 45 percent is caused independently by her other physical infirmities, including chronic obstructive lung disease not caused, aggravated or accelerated by an occupational disease, as well as bronchitis, phlebitis, varicose veins and diabetes, none of which are job related and none of which have been aggravated or accelerated by her occupational disease. This Court must accept such findings as final factual truth.2 The Commission has found as *8fact that Mrs. Morrison’s infirmities other than “chronic obstructive lung disease due in part to cotton dust exposure” were *9 disabling in and of themselves. See Findings of Fact 5, 6, 8, 9 and 11. We are bound by these findings though there is evidence to the contrary.
*10The doctors expressed varied opinions on the extent of the medical disability of Mrs. Morrison. There is a distinction between medical and legal disability. It is up to the Commission to determine the degree of legal disability under the Act. To ignore the distinction between the legal and medical concepts of disability confuses the ultimate issue and obscures the function of the fact finder. We must now determine the proper degree of legal disability for workers’ compensation purposes.
In the field of workers’ compensation law, the statutes control. We must follow the dictates of our legislature on what is or is not compensable.
The parties agree that the evidence is sufficient to sustain the Commission’s finding that Mrs. Morrison contracted an occupational disease while employed by Burlington Industries; that she is totally incapacitated for work; and that the occupational disease caused only part of her total incapacity.
*11Defendants contend that the “resulting from the injury” language in both G.S. 97-29 and 97-30 means that she is entitled to compensation only to the extent o/the occupational disease’s contribution. Hence, she is entitled to compensation for partial disability, not total disability, because the occupational disease caused only part of the disability. Therefore G.S. 97-30, not G.S. 97-29, governs the compensation that should be paid in this case. Those statutes in pertinent part read as follows:
§ 97-29. Compensation rates for total incapacity. — Except as hereinafter otherwise provided, where the incapacity for work resulting from the injury is total, the employer shall pay ... .
§ 97-30. Partial incapacity. — Except as otherwise provided in G.S. 97-31, where the incapacity for work resulting from the injury is partial, the employer shall pay .... (Emphasis added.)
Mrs. Morrison contends that our Workers’ Compensation Act permits no such apportionment of an award in a case of total incapacity. She argues that if an occupational disease acting together with non-job-related infirmities causes total disability the employee is entitled to compensation for total disability.
The North Carolina Workers’ Compensation Act was enacted in 1929. It is not, and was never intended to be, a general accident and health insurance act. “We should not overstep the bounds of legislative intent, and make by judicial legislation our Compensation Act an Accident and Health Insurance Act.” Lewter v. Enterprises, Inc., 240 N.C. 399, 403, 82 S.E. 2d 410, 414 (1954); Conrad v. Foundry Co., 198 N.C. 723, 153 S.E. 266 (1930).
G.S. 97-2(6) defines “injury” to mean “only injury by accident arising out of and in the course of the employment, and shall not include a disease in any form, except where it results naturally and unavoidably from the accident.”
G.S. 97-2(9) defines the term “disability” to mean “incapacity because of injury to earn the wages which the employee was receiving at the time of injury in the same or any other employment.” Disablement resulting from all occupational diseases (except asbestosis and silicosis) is “equivalent to ‘disability’ as defined in G.S. 97-2(9).” G.S. 97-54.
*12When it became apparent that the Act should include a provision for payment of compensation to employees disabled by diseases or abnormal conditions of human beings the causative origin of which was occupational in nature, the legislature adopted in 1935 what is now codified as G.S. 97-52 and -53.
The words “arising out of’ refer to the origin or cause of the accidental injury or occupational disease. Bartlett v. Duke University, 284 N.C. 230, 200 S.E. 2d 193 (1973); Robbins v. Nicholson, 281 N.C. 234, 188 S.E. 2d 350 (1972); Taylor v. Twin City Club, 260 N.C. 435, 132 S.E. 2d 865 (1963); Guest v. Iron and Metal Co., 241 N.C. 448, 85 S.E. 2d 596 (1955); Duncan v. Charlotte, 234 N.C. 86, 66 S.E. 2d 22 (1951); G.S. 97-52; G.S. 97-54.
The words “in the course of’ refer to the time, place and circumstances under which the injury by accident, or disablement resulting from an occupational disease, occurred. Bartlett v. Duke University, supra; Robbins v. Nicholson, supra.
The foregoing legal principles demonstrate that the inquiry here is to determine whether, and to what extent, plaintiff is incapacitated by that part of her chronic obstructive lung disease caused by her occupation to earn, in the same or any other employment, the wages she was receiving at the time she became disabled. It is overwhelmingly apparent that disability resulting from an accidental injury, or disablement resulting from an occupational disease, as the case may be, must arise out of and in the course of the employment, i.e., there must be some causal relation between the injury and the employment before the resulting disability or disablement can be said to “arise out of” the employment.
What, then, must a plaintiff show to be entitled to compensation for disablement resulting from an occupational disease covered by G.S. 97-53(13)? The answer is: She must establish (1) that her disablement results from an occupational disease encompassed by G.S. 97-53(13), i.e., an occupational disease due to causes and conditions which are characteristic of and peculiar to a particular trade, occupation or employment as distinguished from an ordinary disease of life to which the general public is equally exposed outside of the employment; and (2) the extent of the disablement resulting from said occupational disease, i.e., whether she is totally or partially disabled as a result of the disease. If the *13disablement resulting from the occupational disease is total, the claimant is entitled to compensation as provided in G.S. 97-29 for total disability. If the disablement resulting from the occupational disease is partial, the claimant is entitled to compensation as provided in G.S. 97-30 for partial disability. To be compensable under the Workers’ Compensation Act, an injury must result from an accident arising out of and in the course of the employment. G.S. 97-2(6). Claimant has the burden of showing such injury. Henry v. Leather Co., supra. That means, in occupational disease cases, that disablement of an employee resulting from an occupational disease which arises out of and in the course of the employment, G.S. 97-52 and G.S. 97-2(6), is compensable and claimant has the burden of proof “to show not only . . . disability, but also its degree.” Hall v. Chevrolet Co., 263 N.C. 569, 575, 139 S.E. 2d 857, 861 (1965).
When the statutory law of North Carolina is applied to the evidence in this case, the conclusion is inescapable that claimant’s disablement resulting from the occupational disease does not exceed 50 to 60 percent and that the remaining 40 to 50 percent of her disability results from bronchitis, phlebitis, varicose veins, diabetes, and that part of her chronic lung disease not caused by her occupation. These ailments were in no way caused, aggravated or accelerated by the occupational disease. The Industrial Commission so found, with overwhelming evidence to support the findings. The Commission did precisely what the law of this State required it to do. It had no legal authority to award the claimant compensation for total disability when 40 to 50 percent of her disablement was not occupational in origin and was not aggravated or accelerated by any occupational disease.
To be compensable, any incapacity to earn wages, resulting either from an injury by accident arising out of and in the course of the employment or from an occupational disease, must spring from the employment. “This rule of causal relation is the very sheet anchor of the Workmen’s Compensation Act. It has kept the Act within the limits of its intended scope, —that of providing compensation benefits for industrial injuries, rather than branching out into the field of general health insurance benefits.” Duncan v. Charlotte, 234 N.C. 86, 91, 66 S.E. 2d 22, 25 (1951).
When the General Assembly, by the amendment in 1935, extended the scope of the Act to include a specified list of occupa*14tional diseases which are the usual and natural incidents of particular types of employment, the amendment “in nowise relaxed the fundamental principle which requires proof of causal relation between injury and employment. And nonetheless, since the adoption of the amendment, may an award for an occupational disease be sanctioned unless it be shown that the disease was incident to or the result of the particular employment in which the workman was engaged.” Duncan v. Charlotte, supra, 234 N.C. at 91, 66 S.E. 2d at 25; accord, Blassingame v. Asbestos Co., 217 N.C. 223, 7 S.E. 2d 478 (1940); Tindall v. Furniture Co., 216 N.C. 306, 4 S.E. 2d 894 (1939). Proof of causation required to establish a compensable claim under G.S. 97-53(13) is a limitation “which protects our Workmen’s Compensation Act from being converted into a general health and insurance benefit act.” Booker v. Medical Center, 297 N.C. 458, 475, 256 S.E. 2d 189, 200 (1979). Additionally, to be compensable under G.S. 97-53(13), an occupational disease must be “proven to be due to causes and conditions which are characteristic of and peculiar to a particular trade, occupation or employment,” and it cannot be “ordinary diseases of life to which the general public is equally exposed outside of the employment.” These requirements are specified by the statute itself. Accord, Booker v. Medical Center, supra.
The findings of the Commission are supported by competent evidence and are therefore conclusive. They establish the necessary causal relationship of only 55 percent of Mrs. Morrison’s inability to work and earn wages. This was the extent of her disability resulting from an occupational disease. The incapacity for work resulting from the occupational disease is therefore partial and compensation should be awarded pursuant to G.S. 97-30. The remaining 45 percent of her incapacity is not the responsibility of nor a compensation obligation of her employer under our Workers’ Compensation Act which compels industry “to take care of its own wreckage.” Barber v. Minges, 223 N.C. 213, 216, 25 S.E. 2d 837, 839 (1943). Mrs. Morrison’s chronic obstructive lung disease not due to cotton dust exposure is not “industry’s wreckage.” Neither is her phlebitis, varicose veins nor diabetes.3
*15The law we apply today departs from neither statute nor case precedent. Anderson v. Motor Co., 233 N.C. 372, 64 S.E. 2d 265 (1951), first adopted for North Carolina the principle of compensation for aggravation and acceleration of a pre-existing infirmity. It mandates a causal connection between the injury or disease and the employment. In Anderson, we held:
While there seems to be no case on the specific point in this State, courts in other jurisdictions hold with virtual uniformity that when an employee afflicted with a pre-existing disease or infirmity suffers a personal injury by accident arising out of and in the course of his employment, and such injury materially accelerates or aggravates the pre-existing disease or infirmity and thus proximately contributes to the death or disability of the employee, the injury is compen-sable, even though it would not have caused death or disability to a normal person.
233 N.C. at 374, 64 S.E. 2d at 267. In Anderson, the employee slipped and fell under compensable conditions wrenching his back. The employee suffered from a congenital infirmity of the spine which impaired his back’s normal functioning and subjected it to injury more easily. The employee’s physician was of the opinion that he had a “permanent physical disability” of 10 percent and that his disability “could be the result of the last injury received [on the job] or could have arisen before that time.” The Commis*16sion denied the employee any award on the basis that he had not suffered a compensable injury by accident. On appeal the employee contended that the Commission improperly rejected his argument that if his back injury accelerated or aggravated his pre-existing spinal infirmity in such a way that proximately contributed to his permanent partial disability he would be entitled to compensation. This Court recognized the validity of the employee’s argument. It concluded, however, that the Commission did not reject the argument but simply found that plaintiff had not sustained a compensable injury. In the present case, Mrs. Morrison’s argument that the work environment caused her lung disease was accepted in part by the Commission. The Commission did not accept her contention that it caused all of her lung disease or that her occupation in any way affected her other infirmities. In fact, the Commission specifically found that her occupation did not cause, aggravate or accelerate her other diseases and infirmities which cause 45 percent of her incapacity to work and earn wages.
The relevant inquiry under G.S. 97-29 is not whether all or some persons with plaintiff’s degree of injury are capable of working and earning wages, but whether plaintiff herself has such capacity. In Anderson v. Motor Co., 233 N.C. 372, 64 S.E. 2d 265 (1951), Justice Ervin, writing for the Court, noted: “While there seems to be no case on the specific point in this State, courts in other jurisdictions hold with virtual uniformity that when an employee afflicted with a pre-existing disease or infirmity suffers a personal injury by accident arising out of and in the course of his employment, and such injury materially accelerates or aggravates the pre-existing disease or infirmity and thus proximately contributes to the death or disability of the employee, the injury is compen-sable, even though it would not have caused death or disability to a normal person.” Similarly, if other pre-existing conditions such as an employee’s age, education and work experience are such that an injury causes him a greater degree of incapacity for work than the same injury would cause some other person, the employee must be compensated for the incapacity which he or she suffers, and not for the degree *17of disability which would be suffered by someone with superior education or work experience or who is younger or in better health.
In Little, the evidence shows that plaintiff, an over-fifty, obese, uneducated woman, tripped over a mop and fell in a sitting position, resulting in injury to her spinal cord. One doctor rated her physical disability at 50 percent and was of the opinion that she was wholly incapable of resuming her former employment as a laborer. A second doctor was of the opinion that she had suffered an injury to her spinal cord in the neck area; that she had a pre-existing arthritic condition in her neck which was activated by her fall; and that she had suffered a 40 percent disability to the neurological system. The medical evidence further indicated that the injury to Mrs. Little’s spinal cord had resulted in weakness “in all of her extremities” and numbness or loss of sensation “throughout her body”; that she had suffered diminished mobility and had difficulty recognizing objects by feeling of them.
The Industrial Commission found that Mrs. Little had suffered “a permanent partial disability of 45 percent . . . loss of use of her back” and awarded compensation for 135 weeks pursuant to G.S. 97-31(23). The Court of Appeals affirmed. We reversed, holding that the Commission could not limit plaintiff to an award under G.S. 97-31(23) because the fall had apparently caused some unspecified loss of use of both arms and both legs and possibly disabling impairments compensable under other sections of the Act. We remanded for further proceedings saying: “The injured employee is entitled to an award which encompasses all injuries received in the accident.” 295 N.C. at 531, 246 S.E. 2d at 746.
The Little decision mandates the payment of compensation for all disability caused by the work-related accident. Our holding in Little is sound and does not support claimant’s contention in this case. Mrs. Little had no pre-existing, nonoccupational diseases or infirmities that caused any percentage of her incapacity for work. We know that all of Mrs. Little’s incapacity for work, whether total or partial, was caused by the fall. With respect to Mrs. Morrison, we know that 45 percent of her incapacity for work was not caused, aggravated, or accelerated by an occupational disease or by her exposure to cotton dust during the course *18of her employment because the Commission so found upon overwhelming evidence to that effect.
It would serve no useful purpose to engage in a detailed discussion of many confusing and conflicting decisions from other jurisdictions because, for the most part, they are based on statutes and interpretations thereof quite different from our own. It suffices to say that we are not bound by the law of other states. “The decisions from other jurisdictions, while helpful in construing the provisions of our statute, are not controlling; neither is the interpretation placed upon a statute similar to ours, binding on this Court.” Stanley v. Hyman-Michaels Co., 222 N.C. 257, 266, 22 S.E. 2d 570, 576 (1942). The result we reach is consistent with the principle that our Workers’ Compensation Act is not, and was never intended to be, a general accident and health insurance law. Such was not the legislative intent and we should not, by judicial legislation, convert our compensation law into a system of compulsory general health insurance.
In summary: (1) an employer takes the employee as he finds her with all her pre-existing infirmities and weaknesses. (2) When a pre-existing, nondisabling, non-job-related condition is aggravated or accelerated by an accidental injury arising out of and in the course of employment or by an occupational disease so that disability results, then the employer must compensate the employee for the entire resulting disability even though it would not have disabled a normal person to that extent. (3) On the other hand, when a pre-existing, nondisabling, non-job-related disease or infirmity eventually causes an incapacity for work without any aggravation or acceleration of it by a compensable accident or by an occupational disease, the resulting incapacity so caused is not compensable. (4) When a claimant becomes incapacitated for work and part of that incapacity is caused, accelerated or aggravated by an occupational disease and the remainder of that incapacity for work is not caused, accelerated or aggravated by an occupational disease, the Workers’ Compensation Act of North Carolina requires compensation only for that portion of the disability caused, accelerated or aggravated by the occupational disease.
Our Workers’ Compensation Act, as enacted by the legislature and interpreted and applied by this Court, will not support a recovery by Mrs. Morrison for total disability. It is our *19duty to interpret the Act as it exists. This Court is not philosophically opposed to the result sought by Mrs. Morrison, but expansion of the law to permit such recovery is the legislature’s prerogative, not ours.
For the reasons stated the decision of the Court of Appeals is reversed. The case is remanded to that court for further remand to the Industrial Commission for reinstatement of its award based on its findings and conclusions following our remand order dated 23 October 1980 and appearing in 301 N.C. 226, 271 S.E. 2d 364 (1980).
Reversed and remanded.
