Its mostly for practical reasons. The emotional side doesn't particularly bother me. I have trouble climbing, gripping etc, which doesn't help when you're applying for a career which involves lots of hand contact.

And yeah, you're right, I do like to take risks. I'm not afraid of the possibility of horrible side-effects, but I am concerned about the odds of it happening. If theres an 80% chance of severe CS I wouldn't touch the surgery, if there is a 40% chance then its a different story.
