Yeah I have it bad too, I even passed it on to my dog! I know that sounds wierd but I really think I did... she's improving LOL... but not me, sorry. I hope it can improve tho.. good thread des.
I guess it's hard to change ones reflexes because you can't really think differently about it, it's just a reaction. Maybe it is possible to train it. I mean cops must go through training like that. And army guys. Imagine if they started screaming and jumping everytime they were startled. I know you can train to get better reflexes, and probably to control them too.
Maybe you shoulg ask an army man or a police officer. That could be kind of fun anyway
