Those proponents of David Sinclair might be wise to understand Sinclair's motivation: a worldwide multi trillion dollar market for drugs that might or might not work. He's not marketing quality of life but the snake oil of longevity in an overcrowded and overpopluated world whose resources are strained. Follow the money and the motivation. And the sick, unbelievable claim that Aging is a Disease. Are you MAD? Read what the Lancet wrote about that before you buy that bullshit. I have no patience with such idiocy. But that's just me. Sinclair is dangerous. So is the lie that we even should live longer. Look at what we do with the time we already have. That hardly argues for having us stick around longer.
