Not everybody you come across in life fits neatly into a pigeon hole, or behaves in the way that you expect them to behave. Just because you're a wise and elderly university lecturer doesn't mean that you can't also be a totally awesome skateboarder in your spare time. Just ask Tom Winter.
Winter has retired from his lecturing days now, but still pursues skateboarding, which he always used to consider to be an easier and more environmentally-friendly way to get into work than driving, or waiting around for public transport. He became something of an internet hero when the first images of him were posted online, with the original picture often being captured to suggest that he had a formal qualification in something cool. You're never too old to do the things you love - we're just sad that we missed out on the opportunity to sit in Winter's classes!
