 If you need an open-heart surgery, you can't help yourself. You're not going to do open-heart surgery on yourself. But if you can do something like losing weight or controlling your diet or these other things that you can do, your doctor will 100% agree with me that you should try your absolute best to do everything within your power. And then when you get to that limitations of matter, then boom, they come in. And by the way, they help you with whatever means necessary from least invasive to most invasive.
