Well, at age 66 I've just learned to ride a unicycle. I was initially encouraged to be told that anyone can do it. All you need is persistence. So I bought one and got into it. I'll spare you the details except to say that persistence will get you there AND NOTHING ELSE WILL. If you can learn to walk then you can learn to unicycle because it's no more difficult (or easy). The feeling of accomplishment is like nothing else I've ever done. Wonderful fun and exercise. Complements the use of my road bike. No brakes, no chains, no handlebars, no Shimano, no shoe cleats. I'm presently learning to ride backwards - try doing that on a bike.
