Randall Parker links a number of recent study results in a discussion of lifestyle choices and the rate at which age-related damage accumulates in your body.

You can choose to gain decades of healthy life span and avoid hundreds of thousands of dollars in healthcare costs - or not. The better your health and the longer you live, the greater your chance of benefiting further from healthy life extension medicine in the future - getting closer to what biogerontologist Aubrey de Grey calls "acturial escape velocity."
