 I don't think so. I mean, I guess in one way you could say it would if you lose more weight and you're more active and you get out and you do more things than you used to do. You could theoretically be more prone to injury. Well, there was a pothole the size of the Grand Canyon in front of me last night. So I did one of my periodic tumbles. But I'm okay. But if you need to lose weight, if you do fall down, you don't.
