Following a 15 year old around an amusement park that is built on hills will wear you out. Doing so on a warm, humid day will seriously dehydrate you.
The grin on her face after her first water slide, though, was almost worth it. As was calling out to her across a crowd Do you want to take off your clothes first? Boy, that's a strange experience.
Also, riding on a ballistic ride - very fast- is no longer for me. Holy hell. I seriously thought I was going to fall out. I literally staggered off it.
Would I do it again? Probably. But cooler would sure be nice. Humidity sucks.
