Not at your age!

Article Abstract:

The world faces a demographic crisis as people live longer but retire earlier. In many industrialized countries, many employees are retiring way before the statutory age of 60 to 65 because they are offered superficially attractive retirement packages by employers that prefer to employ lower-paid younger workers. This trend is changing the ratio of retirees to workers such that the working population will eventually be unable to bear the cost of supporting a much larger retired population. Theoretically, the demographic time-bomb can be avoided by simply letting older people to continue working. Unfortunately, this is not a realistic solution because many employers refuse to hire older workers on the belief that these people are slow, less adaptable and averse to technology. An alternative is to encourage gradual retirement. This approach is discussed.

Effects of estrogen on circulating "free" and total 1,25-dihydroxyvitamin D and on the parathyroid-vitamin D axis in postmenopausal women

Article Abstract:

The authors investigate the effect of estrogen, a female hormone on levels of vitamin D in 12 postmenopausal women over age 55. The ability of the body to produce a class of Vitamin D was tested by decreasing the blood level of calcium before and after the administration of estrogens. Measurements showed that circulating levels of parathyroid hormone rose in response to the decreased calcium levels. Vitamin D and parathyroid hormone are interrelated and help determine the level of calcium in the body. The authors conclude that estrogen increases the circulating levels of biologically active Vitamin D in postmenopausal women.
