what would cause your carpal tunnel?

i do not have carpal tunnel. and for that i am grateful. my MOM had tendinitis in her thumbs that required surgery from playing so much bridge and shuffling cards. if i did develop carpal tunnel, it would most likely come from opening roasted peanuts. i can't get enough of these things- it must be part of my squirrel heritage.

another possible cause of my nonexistent carpal tunnel would be the game minesweeper. i have gone through phases where i played that game 8 hours a day. usually while procrastinating from studying.
