just been reading this thread .. and its been quite interesting. To wear a helmet or not to wear a helmet .. it is eco individuals right to choose as in this country it isn't a legal requirement. I Ride a Motorcycle also and legally have to wear one, I have seen even on a bike helmet the damage that can be caused coming off at 20 - 30 mph .. which some cyclist can manage on there pedal powered machines (sadly im not there yet). I would always wear a helmet when going out on my pushbike. The risk is too great not to, drivers seem to be less forgiving and the whole, im bigger than you there for I have the right of way mentality seems all but here to stay (contrary to the Highway Code).
For the sake of looking like a tool I would much rather stack my chances if the worst should happen.
I was speaking to a friend who remembers that when Motorcycle helmets where safe compulsory there where riots about having to wear them, as people just didn't want to.
So everyone has there choice to wear or not to wear that is the question, but its just up to you and if you would want to take the risk. As if something should happen then hindsight would become much more clearer.
The way I see it .. bones can heal .. brain damage not so much
This is just my thoughts and opinions and I always respect others and won't preach about them having to wear one.
