ha, nope, I'm a structural engineer. I was an Active Army Officer and I was in charge of Ranger and Sapper training for new Army officers. I had to research a lot of stuff about physical fitness and nutrition. I also got to go to a lot of seminars like crossfit, army combatives, endurance training and nutrition, etc.
Anyhow, long story short, I'm just like everyone here I suspect. Found somebody that knows their ish (ADARQ, Lance, Kingfish, etc) and listen to what they say.
