At the age of 42, I had two kids grown and out and the last one a senior in high school. I decided to change careers. After 6 years as a reserve Deputy Sheriff, I started the Academy with a bunch of 20 somethings. That was 14 years ago and I haven't regreted it. When you are young and have kids, your focus should be on them and raising them right but once that is complete, it is time to do what makes you happy. Life is too short to waste doing something you don't enjoy.
