" Eating fruits and vegetables is vaguely logical. Get sleep. Don’t live in the most polluted parts of the world. Don’t smoke. Don’t do unsafe things like skiing and hang gliding, which are inconceivably more dangerous than eating ‘unhealthy’ foods. Exercise is pretty likely good for you. Don’t drink too much alcohol—one or two drinks a day. And that’s about it. "
