It is nice to have your children and your wife know that their father/husband is a big bad man
I forgot to mention, it is also part of my job too. I am very prone to robbery. So when the thugs come in to the store looking to start something, first thing they will spot is me being 2x their size as well as the handle to my S&W Magnum poking out of my jeans pocket. So intimidation is crucial to me as well so that I can prevent issues. It also stops the guys from looking at my girl. They know they'll get a beating lol.
Those aren't reasons WHY I am do this but they are definitely benefits.
