i want a helmet!

Running every day works like a charm. After a bit, your lungs get used to it, and your legs hold up.
...that is if you don't have a wipe-out on a racing bicycle. My shitty knee is now bruised and missing a large skin patch. So is my right elbow. After this close call, I'm seriously interested in buying a helmet.
However, I've gone to class and trained.
I'll run as soon as I'm through this.
