Life Expectancies Still Increasing
Actuaries are generally on the conservative end of aging research, but you'll still see a recognition of the prospects for healthy life extension in their work. The BBC has the latest: "The life expectancy of men who are 65 may rise by another three years during the next decade to nearly 90. ... For the first time, the authors of the actuaries' continuous mortality investigation (CMI) have refused to make an official projection of future life expectancy based on their new mortality research." A continuing rise in life expectancy is to be expected as medical science advances; our bodies are simply complex machines, so better repair and maintenance techniques lead to longer, healthier lives. Still, this incidental healthy life extension is a slow process - directed research into repairing the root causes of aging would be much faster.
