People often ask me the same question:
“What’s the single most promising anti-aging measure coming in the next decade?”
If you care about where longevity medicine is truly heading, this one’s worth a look.

'They hold hands, they embrace, they kiss': The woman who changed our view of chimps - and human beings
In 1960, Jane Goodall began her groundbreaking field study by living among chimpanzees in Tanzania. In 1986, she told the BBC how similar chimps and humans really are.
