Human surivorship theories for the FUTURE
- 1. Rectangular theory: Hayflick and Fries and Crapo
- life-expectancy will increase, but MAXIMUM lifespans will NOT

- BOTH avg and maximum lifespan will increase
-
Anti-aging interventions
- 1. Calorie restriction
- 2. Pharmacological interventions: antioxidant vitamin supplementation, C, E, niacin, B-carotene and B vitamins, and MELATONIN, possibly DHEA
- 3. Biological interventions: growth hormone injections (watch for high systolic BP), drugs to reduce body weight, tissue growth from in vitro cell cultures
- 4. Lifestyle interventions: reduced toxin exposure, no smoking or alcohol

Social effects of Successful aging
- 1. Pessimistic view (HAYFLICK): Increased longevitiy = bankruptcy of Social security system, drain health care resources and cause impovershed elderly
- 2. Optomistic view (WALFORD): Increased longevity = Increase retirement age, lower health care costs
- 3. Gerontological Society of America viewpoint: with Hayflick
- Peter Medawar: seen as optomist, society has had to adjust to human nature before and should be able to adapt to increased longevity in the future
