It's weird, I rode motorbikes off road as a teenager and wouldn't have dreamed of not wearing a helmet, heavy boots and gloves etc.

Just bought a new bike to commute to new job (starting on a 125 and working my way up since not been on a bike for 20 odd years) and while a helmet was thrown in it'll be the first upgrade after proper jacket/pants.

I still don't get why it's even a debate, I've cracked two bicycle helmets from accidents that weren't my faults in impacts that without them would have been vastly worse.
