An assessment of headgear based on severity and likelihood of brain damage
After a bit of research, I have updated my physics and martial arts blog with an assessment of headgear and helmets based on severity and likelihood of brain damage the across several different sports.
The thirty second version is "Boxing and baseball headgear help reduce brain damage, but only slightly. Football headgear reduces brain injury only marginally more than the other two, but encourages much harder hits, resulting in a net increase in brain injury due to the headgear."
Also, turn around and run away from headgear with a face guard on it.
Thoughts? Personal experiences or anecdotes to add some color?
