Within the last two years, both major American parties have been dealt punishing blows for allowing their party leaders to literally age themselves into debilitating senescence. 

Have we learned our lessons yet, or will history repeat itself? Can the health of the nation withstand it again? This is an important story I’m not hearing tonight amidst the positive stories of sweeping change.

Bookmarked Hayflick, his limit, and cellular ageing ( Nature Reviews Molecular Cell Biology)
Almost 40 years ago, Leonard Hayflick discovered that cultured normal human cells have limited capacity to divide, after which they become senescent — a phenomenon now known as the ‘Hayflick limit’. Hayflick's findings were strongly challenged at the time, and continue to be questioned in a few circles, but his achievements have enabled others to make considerable progress towards understanding and manipulating the molecular mechanisms of ageing.
