I worked a lot of trauma in SoCal and he is right. I worry about it every day I ride.
But that doesn't mean you shouldn't ride because, the probablity is a heart attack will kill you eventually.
Still, I am amazed how many lectures I get regarding diving, things way less dangerous.
So....maybe I'll ride with just one ear bud in.

I really hate it when friends do that, because I always take it as "a sign from God" lol.
I don't mind death, I just really don't want to be a vegetable.

I ride with my man who is like messenger boy, thats how I know I am going to get hit. (I am not good enough to ride that way) People yelling "stupid" out of their cars is what tipped me off.

Oh? ...and when people send you links about that stuff, NEVER open them.
