Concussion denial: in mixed marital art (or UFC) fighting like bike helmet debate?

[Nandy]

Exactly- that's why I never take my full face helmet off at any time. Imagine the damage you could do just tripping while walking through the market or rolling out of bed! I certainly never set foot inside a motor vehicle, where 20% of all of TBIs occur (an activity where professional racers wear helmets religiously, and the idea of regular people using helmets during this activity is laughed at).

TL;DR- humans are incredibly bad at evaluating risk, and I hate to see bikes singled out and uniformly and illogically thrown under the metaphorical bus. Australia is well-known as very unfriendly to bikes (universal helmet law) and The Netherlands is pretty well-known as bike heaven (very low rate of helmet use). At least differentiate "cycle sports" from "bikes".
