back in the day i was riding shotgun on a friends bike, wearing a helmet but it had no visor, so when we hit a swarm of moskitoes it allmost took me out.
HAd to ask my friend to stop the bike so i could rub all the damm bugs out of my eyes, and spit the ones in my mouth out.
Dident mythbusters do a test on what it will take to take a man out ? think they ended up with a fairly large animal, but that was kill a man by impact not hit a man and make him Loose control of a bike,,, and then kill himself.
