Besides; bicycle helmets look....well....stupid. They usually come in bright florescent colors and are shaped as if they would fit some alien's skull. Nothing says "dork" like wearing one of these things, so I pretty much made up my mind I wasn't going to mess with getting one for myself.
Until I took a spill off my bike.
And I was getting really bloodied and bruised.
I was starting to think to myself "that old saying about once you learn how to ride a bike you never forget is a bunch of shit" but realized that I still knew how to ride a bike, I just wasn't as pliable as I was 40-50 years ago. The bones and joints are not as flexible. I have a lot more mass. I don't heal as fast. Plus, I really ought to have a bit more sense than when I was an eight year old. At that age I more or less thought I was immortal and indestructible. Now I know better and know how fragile body parts can be, especially the head. I can't afford to lose anything....most specifically what little I have in my skull.
