2 instances to speak of:
1st: I got my wisdom teeth taken out and developed an infection called "dry socket". For those of you who know what I'm talkin' about, you know how much this sucks azz!!! I couldn't sleep for 3 days straight and I just sat in a chair with ice packs on my face for those entire 3 days. I wanted to shoot myself.
2nd: On my first day of skiing in Michigan I got the bright idea of deciding to tackle the baddest black diamond hill at the restort. The name "Awful, Awful" should have registered in my head, but I was blinded by my own possible glory. Just wanted to be able to say I went down one. Needless to say, I didn't make it. Made it about halfway down before I hit a bump and went head-over-heels. I probably fell, tumbled, rolled, for a good 200 yards down the mountain. My skies, poles, hat, glasses, and 1 boot exploded off of me after the 1st 100 yards or so. I ended up tearing some ligaments in my knee and shoulder. To top it off, I had to crawl back up the mountain to retrieve my stuff. My knee still really bothers me some days.
The morale of this story: Don't be blinded by the glory!!!!
