It’s the simplest thing in the entire world.’”

Probably would have happened sooner if my childhood insecurities weren’t exacerbated by years of public mockery about my body by press and interviewers,” he wrote via Instagram. “So the idea that the media tries to play me by stalking me while surfing and printing photos like this and it can’t phase [sic] me anymore is dope. I’m 37 and finally love and accept myself. This isn’t a ‘good for me’ post. And it’s definitely not a ‘feel bad for me post.’ It’s for the kids who don’t take their shirt off at the pool. Have fun. You’re wonderful and awesome and perfect. All my love.” We love you, Jonah!
