I always enjoyed running around in the woods like an 8 year old. That burns most of my junk food diet, so i don't have any weight problems. Recently i started some other types of exercises, till now everything i tried, except running, got boring, but we'll see if i can actually stick to a regime or not. Apparently Linus has the same problem, but i at least found one thing that doesn't bore/frustrate me. He could try soccer, that kept my interest for the whole summer until it got boring last month.
