David Agus, author of The Lucky Years: How to Thrive in the Brave New World of Health, says we’re living in a golden age when the latest science and technology can customize care. Tools that track behavior like how much we sleep and walk are now widely available. Such technology, says Agus, can help us control chronic conditions, reverse aging, and improve health overall. In his conversation with Jessica Herzstein, a doctor who specializes in preventive medicine, he also talks about the Covid-19 pandemic and when we might expect to have a vaccine.
