Ultimately it has to be your choice, but for me, I've been on the unpleasant end of a potentially fatal bike crash and I won't be giving up riding.
I know that it's dangerous, but I love doing it, so sod it, I will.
I could get squished by a Volvo mounting the pavement and plowing through a bus stop tomorrow.
All those close to me know I love riding bikes and while they may not understand it, they respect that if the worst should happen, at least I've enjoyed myself and not compromised something I love so much.
Is that selfish? I dont think so. I look at families and stuff as reasons to enjoy life and come home to them.
I just think of this happening:
Clicky (not for faint hearted)
Then I go out and ride.
