Why do we do this to ourselves?

So today Lisa and I went to the beach. The water was freezing (61 degrees), the sun was hot, we were sweating, the sand was blowing and sticking all over us, we couldnt get comfortable as we were laying there, we got sunburned, we looked nasty, etc.
On the way home were talking about the day and we both said...why do we do this to ourselves? the only really fun part of the day was hanging out together...but we can do that in a skin-cancer-free environment! HA!
so, we both decided that next time we want to go to the beach, we wont. we will find something air-conditioned and clean. funny how we didnt think of this earlier. we've been doing it for years! maybe we are getting old?
