I am surprised people are so flippant about injuries to the head. How many times do we hear stories of people dying from being punched and hitting their head on the curb/ground ? Or the long term effects of concussion.

Helmets work. Governments around the world wouldn't be making them mandatory just to screw with people.

I don't know about your general claim. CFLs are highly toxic under non-ideal real-world handling conditions, and governments love mandating those.
