sledding.

Last night I went sledding. Sarah, Me and the FHE bros, Buzz, Jeff and Justin...it was waaaayyyy fun. My toes nearly froze off but all in all I had a blast. So last night I got home and started to realize that my butt and tail bone hurt a bit...then as I went to bed it hurt more and more until now. Today I'm a lot sore. But I guess i'm just curious, is it still worth it? I think so. So the question is...why do we do these things and injure ourselves but consider it still completely worth it? Is that normal or ridiculous? Pretty sure I'd do it again if I had the chance.
