I came second in the 2016 EU Procrastination Championship as Will Tomorrow, my opponent, never bothered to show up...

Running: I know some swear by it and report getting a natural high doing so. But even when I was really into sports - there was a time I played in 3 basketball teams at the same time - jogging just didn't do it for me. I got bored after 5 minuted and started to wonder about Life, the Universe, and Everything.

Swimming might be a good alternative?
