You really do exhale when shooting guns? you must be a bad shooter thenhehe.
Well I am trained for shooting, ive been in the army for 12 years, went to so many military schools that trains shooting, M-16, and Beretta 9-mil. and I can tell you this, first thing they are going to teach you for shooting is that when you want to shoot, you really do have to Mute Breathing while you aim/shoot.
Deep breath, let half out, then squeeze (never pull) the trigger. My training...
Funny, thinking about it, I carried this over to pool.
