"Getting old ain't for sissies."
If we're going to make this a serious thread after all, directly against the intent of the one who started the thread... I take a philosophical perspective. I know I will get older and my abilities will diminish. What I cannot do in the future, I will not do. If it needs to be done anyway, I trust God will have someone in place to do it.
I will still do what I can as long as I can though. I park at the tail end of the church parking lot because I can still walk just fine, and I'm not parking closer until I get a LOT older and more stove-up. But when I do park closer, I will have good reason to and I'll have no shame about not being able to walk that far any more.
