Why Sleep Is the Key to Living Longer

Today, at the age of 63, I find myself in peak health—physically, mentally, and energetically. A wide range of performance metrics and biomarker data bolster this belief. I’ve gotten here not by luck, but by effort and by prioritizing healthspan: the amount of time you spend in good health, free of disease. I’m on a personal mission to maintain this optimal health for the next decade, so that I can intercept the next generation of therapeutics under development that are promising to slow, stop, and even reverse aging.
