Just a quick note on Bings post, taking up a martial art may be the perfect activity for many people on this site. Not only can you get in shape, but you will learn some self-defense techniques (more or less, depending on how 'martial' the art is) and do it with a group of people who are WAAAAAY nicer and more approachable than people in your average gym. Classes are usually made up of all sorts of people, including athletes, housewives, businessmen, kids etc. Everyone welcome and everyone is very helpful, since they all started the same way, on the lowest rung of the ladder. One of the things I love about it is that you get out of it what you put in to it, work harder, gain more, learn more. You can make every hour a good workout if you want to, you can practice in your living room if you need to, you can develop a warrior mindset, you gain grace, power, flexibility, endurance, discipline - what's not to like? Keep up the good work! - M.W.
