Not attempting to explain everything... but wearing a helmet doesn't prevent you from being knocked unconscious OR from getting a concussion. A concussion involves your brain moving inside your skull... no helmet currently in use can 100% prevent against that. A helmet will protect your skin from damage in a collision and likely prevent bones from breaking in your skull... but doesn't do much to prevent concussion or loss of consciousness.
Not saying that applies to Morgan in this episode... but just going the extra mile here to explain helmets...
...The more you know... *starburst*
Very valid points, however......, if a helmet won't protect you from being knocked out when you fall from standing up (less than a 6 ft drop for your head with no real velocity), it would never pass certification, therefore never be on the market.
Where is that beating a dead horse emoticon?
