TWEETABLE QUOTES
“I wrote the book because there’s a lot of really interesting technology and things people can do in their daily lives, I believe, to live significantly longer and healthier. But, I also wanted to start the conversation because I felt no one was really saying the kinds of things that I was saying.” (08:15)
“I think that the major driver of aging, put simply, is a loss of information.” (10:19)
“I think it’s worth clarifying that the sirtuins are protectors of our bodies, but they can also cause aging by being distracted too much.” (25:11)
“It’s all about being uncomfortable. Our bodies would much rather sit in a chair and eat popcorn. There’s a whole industry based on that.” (26:19)
“I like to joke that scientists like to fight because the stakes are so low.” (42:41)
“We can predict, very accurately, how old someone is biologically. And that’s not so much related to birthday candles. It’s more about how you’ve lived your life. Twenty percent of your age will be genetic and eighty percent will be how you’ve lived.” (46:59)
“What I don’t know is how to bring people back from the dead, but I think we’re getting close to being able to keep people alive in a healthy way for much longer.” (57:31)
