Document Summary

Differences in the way bodies look over time: decrease in height and fluctuations in weight. Between mid-50s and mid-70s men lose about 1 inch and women 2 inches. Changes in posture: weight gain then loss. Sarcopenia: degenerative loss of skeletal muscle, and loss of muscle strength, no difference in the rate of muscle change between men and women. Osteoarthritis: starts in your early twenties, typically, degeneration of cartilage in the joints painful, progressive, starts in 50s or 60s, inflammation of the joints, normative, just uncomfortable. Rheumatoid arthritis: non-normative degeneration of cartilage in joints, typically genetic, swelling of the joints, much more painful and destructive, can prevent people from doing many things. Brought about by lack of calcium intake. Fair-skinned women are more prone to developing it. Gender differences: compensation cosmetics, hair dyes, plastic surgeries. Appearance as opposed to actual losses in strength and endurance: exercise and resistance training is useful up to age 90.
