250000 deaths 12% have been estimated to be due to lack of regular physical activity.
Physical activity decreases death rate, reduces body fat and weight, improves lipid
profile, improves insulin sensitivity, increase cardiovascular endurance and aerobic
capacity, maintains bone mass, increases muscle mass and strength, increases postural
stability, balance, and flexibility, and improves well-being, sleep and cognitive function.
Sarcopenia – muscle loss associated with aging
Two most common nutritional problems of American elders: overnutrition and
undernutrition. Obesity, malnutrition, and unintentional weight loss.
BMI between 19 to 22 provides best health and lowest mortality.
Good eating habits can prevent or reduce the progress of many chronic diseases.
Sexuality Chapter 11
America is a youth-oriented, consumer-based society. Cosmetic industry takes advantage
of this. Sexuality of older people isn’t taken seriously. Sexual activity is practiced by
elders in their 80s and 90s. Starr and Weiner questioned more than 800 elders 60-91
about sexual attitudes and feelings. 96% women and 99% men answered yes to liking
sex. One study of 1202 white married men 55-94 showed intercourse frequency to be 3.6
times a month among 55-59 but 1.3 times a month for 85-94. Reduced sexual activity
with advancing age and declining health affects activity and satisfaction. Another major
factor – availability of a partner. Health problems and medication, boredom, career or
economic pursuits, mental or physical fatigue or infirmity, overindulgence in food or
drink, and fear of impotence. Masturbation maintains elasticity and lubrication of vagina
for women and preserves ability to have erection for men. Orgasms reduce stress and
induce sleep. These surveys are not 100% accurate.
