I go shooting a lot. Why are a lot of gun owners OBESE and scared of home invaders, but not a coronary?

5'4" and 110 lbs might be careful not to talk anywhere other than here about who's fat and who's not at the firing range least one of those fatties makes a good example of you. For a light weight such as your self you should ask these guys about their expertise and experience. You could learn a lot I'm sure.
