Older, wiser and perhaps healthier? It may sound too good to be true, but Sue Armstrong, author of Borrowed Time: The Science of How and Why We Age, says that growing older doesn’t have to lead to infirmity. Science is finding ways to intervene in the aging process, and to improve the quality of our later years. After all, some organisms on Earth live for centuries, so there may be good models for rethinking and easing the process of getting older. Armstrong says that while there’s no magic elixir for aging, there is a more hopeful future ahead.
