Document Summary

Skin most vulnerable to a series of age-related changes. Varicose veins on the side of the legs. Toenails grow more slowly and become yellowed, thicker and ridged: fungal infections usually develop here -- causes the nail to thicken and separate from the nail bed. Photoaging caused by exposure to the sun. Uv rays accelerate the process of cross-linking, cause mutations that alter protein synthesis by the cells, and increase the production of free radicals. Hair color production of melanin slows and eventually ceases. Hair thinning results from the loss of germination canters that produce hair in the hair follicles. People get shorter as they get older: more pronounced in women o because of loss of bone mass in the vertebrae. Lean tissue, or fat-free mass (ffm) decreases and bmi increases. Pattern of body weight in adulthood is an upside-down u-shaped curve middle-aged spread.
