Just came across this very recent GQ interview with David Sinclair!

One of the things he mentioned which I found interesting was that he "sleeps on a bed that adjusts his body temperature while he's asleep to get the deepest of sleep".
There's also a link to his recently launched venture, Tally Health, "an at-home test conducted with a cheek swab that will report back with your own biological age. From there, you’ll receive some multivitamins that promote healthy aging, as well as lifestyle tips like diet and exercise" (https://tallyhealth.com/).
