Officially as of last month 5'7 1/2 measured by an NFL scout at our college showcase. I'm feeling mighty tall about now. But I took a Fathers Day picture at the gym with me and my two boys at the gym after we trained and felt like a midget 
That can happen when you have kids, boys particularly. My son is taller than I am. To balance things out, my daughter is more her mom's height, which was a few inches shorter than I. On the other hand, my dad was 6" taller than I was at my tallest.
5' 71/2" is not all that short. Why all those short comments/jokes about you?
