Mechanisms of Human Longevity
Supplemental discoveries
1. The frontier of survival is advancing because senescence
(the increase of mortality with age) is being postponed.
The major discovery— The advancing frontier of survival.

Determinants of Longevity
• Average lifespan in a population
• Biomedical knowledge, health care system, standard
of living, education, healthy behavior, environment
• Variation in lifespans among individuals
• Healthy behavior: listen to your mother
• 25% genetics, 10% childhood, 65% adult life

methods
• Be very cautious about using expert
judgments about the future

The Future Will Be Different from the Past
• In next decade or two, progress against cancer
and dementia and in developing genotype-specific
therapies
• Then progress in regenerating and eventually
rejuvenating tissues and organs
• Accompanied by progress in
replacing deleterious genes
• Aided by nanotechnologies (nanobots)
• Perhaps in a decade or two, probably later, progress
in slowing the rate of aging (as opposed to further
postponing aging).
