Yep, the older you get, the longer it takes to come back from any physical setback. And that's true for everything from surgery to bumping your arm on something and getting a bruise. Annoying as hell.
Not saying that a mere bruise is the same as having hernia surgery, but it's kinda the same concept. I had an itch, I scratched it, no big deal, except my arm fucking hurt when I scratched it. Why? I look, and there's a bruise from when I bumped into a shelf three or four days ago. I'm like What the hell? How can it still hurt? I bumped it four days ago!
