    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.

    • Be very cautious about using expert

    Directly Forecasting Record Life Expectancy

  • 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).
