Eek, I might be old

Alright, so I don't feel or act old most of the time, which is good. Today, I feel about 85. This weekend was Tracy's weekend with the kids so I worked two doubles. In my defense, they were kick-your-a$$ doubles (32 hours in two days in an outdoor restaurant), but still, I'm beat after them. I used to be able to do that no problem, but every part of my body hurts. I don't like it, not one little bit.
