“I don't understand people who say, 'Oh, I don't want to take take resveratrol cuz we don't have any proof that it works.' Well, dude, it costs 2 cents a day. It's never hurt anybody as far as we know.”
Sinclair argues that resveratrol is low-risk and inexpensive (approximately 2 cents per day), and has never hurt anybody as far as is known, making the risk-benefit calculation favorable.
