I can try:
At low speeds, a helmet is extremely useful at reducing the effects of an impact - abrasions, cuts
and suchlike. At high speeds, forget it.
When I was hit by a car coming the other way, I got brain damage. This was caused by my brain having
momentum and slurping at my skull when my skull stopped moving, then bouncing back from that and
slamming into the rear of the skull, causing the damage and internal bleeding. Momentum would have
been the same with or without a helmet. I wasn't wearing one, so I got a split ear from the
collision as well as the brain damage. The helmet could well have lessened the damage to my ear. I
still don't wear one, though. Maybe as an after-effect of the brain damage.
