Letter to the Editor Pineal Effect on Longevity
نویسنده
چکیده
A RECENT study of survivorship among the blind in Massachusetts [1] reveals that blind persons under 65 suffering from retrolental fibroplasia had a significantly better survivorship than other blind individuals . This may be the result of a pineal effect upon longevity . Ten year survival rates for major affections in the Massachusetts study (see Table 1) reveal that blind males under 65 with retrolental fibroplasia had a 96% observed survival . The expected survival of the general population in the same age group, calculated from State Life Tables and weighted according to age distribution within the blind group, was 98% [2] . The blind category with the next closest observed to expected survivorship, affections of the cornea, had 76% observed survival as opposed to 86% expected survival . The difference between the survival of the retrolental fibroplasia group and the corneal affections group was highly significant (p < 0 .005) ; the former had a survivorship not significantly different from the general population, while the survivorship of the latter was much worse than that of the general population . The ten year survival picture for females under 65 was similar. Blind women with retrolental fibroplasia had a 99% observed survival and a 98% expected survival . The female group with the next closest observed to expected survivorship, myopia, had an 87% observed and 91% expected survival. The difference between the survival of the retrolental fibroplasia group and the myopia group was significant (p < 0 .025) . The blind have long been known to have substantially poorer survival rates than sighted groups at all ages up to 75 [1, 3, 4] . For besides suffering the complications of systemic diseases, such as diabetes, which often lead to loss of vision, the blind are especially prone to accidents . This accounts for the very poor survivorship seen in most of the blind groups . However, in retrolental fibroplasia, affections of the cornea, and myopia, there is no significant association of life-shortening systemic diseases . And although all three

Obesity is a complex multifactorial disease. The worldwide prevalence of obesity has doubled since 1980 to an extent that nearly a third of the world’s population is now classified as overweight or obese. On the other hand, sports scientists have suggested exercise for the prevention of further spread of this disease. In addition to exercise, the use of natural fat-burning supplements, such as ...
