You know you're getting older when...

You get unexplained injuries that nag you...for example, today, I woke up, and for whatever reason, my right hamstring is tight and sore. Not horribly sore, just tweaking me enough to let me know it's there.

Now, I did nothing physically strenuous yesterday...nothing except walk up and down stairs on occasion. That's it. It didn't bother me yesterday, but lo and behold, here it is today. Probably it will go away tomorrow.

That's about it for now...
