Population norms, but not individual norms, can be established for any physiologic parameter and its laboratory measurement. Yet, variability is the hallmark of aging, and physiologic change is no exception; as a result, extrapolating from norms to individuals is done with less confidence in the elderly. Many normal elderly persons show little or no physiologic [...]
Deviations in results (which, in many cases, were more likely the result of disease than of normal aging) were noted in 5% to 10% of the population for the following: women > 80 yr, a low hematocrit; women 65 to 80 yr, elevated calcium levels; both sexes of both age groups, reduced serum phosphate concentrations [...]
Prostate-specific antigen (PSA) levels rise with age; the levels are typically about 2.5 ng/mL in men 40 to 49 yr of age, increasing to about 6.5 ng/mL by age 70 to 79. PSA levels may increase as a result of conditions other than cancer, such as benign prostatic hyperplasia or a prostatic infection, or briefly [...]
EFFECTS OF HORMONAL CHANGES Testosterone An age-dependent decrease in morning and mean 24-h plasma levels of testosterone occurs; free testosterone levels are less affected. A marked decrease occurs only after the seventh decade. Diet does not seem to influence levels significantly at any age. Smokers have higher testosterone levels than nonsmokers in all age groups, [...]

Persons who decline coverage but later change their minds must pay a surcharge based on how long they delayed enrollment. Participants may discontinue coverage at any time but must pay a surcharge on the premium if they re-enroll. Part B covers physician services and physician-prescribed services, such as hospital outpatient services, including emergency department care [...]
Part A of Medicare is supported by a payroll tax collected during a person’s working years. Part A represents paid-up hospital insurance for Medicare-qualified retirees, who pay no premiums during retirement. Generally, only people who are eligible to receive Social Security monthly payments are eligible for Medicare. Persons who never worked or who did not [...]
Individually, Medicare, Medicaid, Medigap, and private long-term care insurance have shortcomings in providing comprehensive geriatric care, which includes the medical, nursing, and supportive needs of the elderly patient. Medicare excludes long-term custodial care and many preventive services; Medicaid belatedly intervenes after the patient is impoverished; Medigap, like Medicare, excludes long-term care and outpatient prescribed drugs; [...]
