Getting older bites

So I'm just 39 this year (a few weeks ago actually) but parts of me are falling apart. If you ask my darling, loving husband, he will tell you that I've been falling apart for years now - teeth (crowns and laminates), vision (bifocals), and knees (surgery at a young age), but now my back has succumb to age as well. Actually my back has given me fits on and off for years but this time it's because I painted my toenails. Yes, you read that correctly. The act of painting my toenails has caused me back pain. Last Fall it was shelving library books. The act of putting the books on the lower shelves in the school library made my back seize up. This time it's the toe nail polish, and life just isn't fair. I'm a big fan of changing my nail polish on a regular basis, but without having to hit the salon. I guess it's time now to start doing that. I better start popping in for a quick polish change occasionally or else I'll end up who knows where, but face up. But the whole can't reach my toes because it hurts thing? Well that really bites. I love my chiropractor and all, but I'm not nearly old enough to be going through this. And the worst part is - I know that this is just the beginning. Ugh.
