Smash Mouth was definitely on to something when they said, "The years start coming and they don't stop becoming." They don't. They really don't.
I feel like once you realize you're on the wrong side of 25, and then the wrong side of 30, and then find yourself approaching the dreaded 40s, time just speeds up and never slows down again. Suddenly you're this middle aged person who goes to bed at 10 PM every night and who now regularly fits new body aches into every conversation you have.
If anything of this is sounding familiar, I think you're really going to relate to these quotes.
