One of my riding buddies was as hard headed as you.
I only wish he was still here to tell you his story.
You are correct,its your choice and your brain,but,again,I agree with what has been echoed...
if you feel your brain and life are worth nothing,then don't wear any protection.
Nancy and I use to ride sometimes without a helmet.
Then when we realized that a helmet would have saved our friend Click Baldwin we decided to start wearing them. (all the time)
Also, after seeing the tears, heartache and agony of families that have lost loved ones, we realized maybe, a helmet might keep that from happening.
if you feel your brain and life are worth nothing,then don't wear any protection.
We have loud pipes, we have loud horns, we have bright lights just so people can know we are there.
With the above what are you trying so hard to protect but then leave your brain uncovered?
I wear a helmet not because I have to, I wear it because I want to and feel it's a smart thing to do.
Again,
if you feel your brain and life are worth nothing,then don't wear any protection.
