A buddy of mine says "The only difference in wearing a helmet or not is whether you spend a week in the ICU before you die." He's a doc, rides a Harley, and never wears a helmet. For me, I always wear one.
I had an RN pal who rode a Harley. He used to say that kind of thing all the time. He also used to excoriate me for wearing a helmet on my motorcycle 'cuz:
"You're just going to end up paralyzed when that helmet breaks your neck--or in a coma."
He said proudly: "I'd rather be dead."
Drunk, he hit a curb in Sturgis and went over the handlebars at about 20mph and landed on his head.
He was in a coma for 8 months until he mercifully died of a heartattack.
The best one was my pal, Jay, who busted his nogging on the pavement tooling around on a dirtbike.
He was never right again: He developed a fascination with my pal Matt's weight. Every time he saw, or talked to Matt, he would try to trick him into getting on a scale or telling him what his weight was.
"Yeah, Matt...." He'd say: "I'd like to get you on a scale!" Weird!
I don't always wear a helmet. Sometimes it's nice not to, but it's not smart....
last year I had a 1" rock get thrown up by a car in front of me on the highway. It came over the windscreen and hit me square in the middle of the helmet visor. It sounded like a gunshot and it took a nice nick out of the visor--we admired the nick when I got to work.
The guys wearing doo-rags on the highway obviously haven't been hit in the chops by a rock yet....
