Evolution's Purpose
- The evolutionary purpose of life may be to pass on genes, directly or indirectly, by helping others.
- This explains behaviors like menopause and altruism, challenging the idea that we exist solely to reproduce.
Body's Decline
- The human body gradually declines in function as we age, impacting physical and metabolic processes.
- Mental capacity also declines, but the rate can vary significantly depending on the activity, like chess.
Mortality Doubling
- After age 35-40, the human mortality rate doubles approximately every eight years.
- This 'clockwork doubling' continues into old age, leading to either a maximum survivable age or a 'Russian roulette' scenario.
