Getting too old?

I had one of those getting-too-old-for-this-shit moments last week.

I went out to see the pioneers of melodic death metal, In Flames. They played a great show. But about half way through I got kicked in the back of the head by a crowd surfer, which caused me to sit out the rest of the show in the back with the toe-tappers. My fucking neck hurt for three days. I so hate to say it, but I fear the next show I go to, I'll be staying off the front floor.
