Good for him, what a lucky guy, but having said that journalism like this actually really annoys me. I am very fit, do long distance runs 3 to 5 times a week, half marathons, marathons, weight training. Yet somebody at work mentioned to me (what I assume was) this article and said "oh by the way did you know you can reverse your diabetes by exercising and being a bit more active, I actually read a story about a man with type 1 who improved his fitness and no longer needs insulin". Cue me trying to explain the reality and "if only it was that easy".
