First you need to figure out what kid of gearing it is, and what's important is the number of sprockets at the rear wheel. I'm assuming that you're talking about a 6 speed rear for the 18-speed and a 7-speed rear for the 21-speed. If that is the case there is a risk that the 6-speed rear has a narrower hub than the 21-speed. This can make it awkward. But the biggest issue is probably the shifters. a shifter intended for 7 rear sprockets will not shift cleanly over 6 sprockets.

NO.
If one ran into an embankment they would most likely be hurt. If you hit one with a car, your car would be damaged. If you hit it on a bike you could have serious injuries depending on your speed.
The Wheel of Hurt was created in 1966.
yes
Um ... i would NOT let her go she could get hurt bad
No.
Can be. It gives more speed than going on foot, so falling off a bike can hurt more than stumbling when walking. Bicycling often brings the rider out in traffic, where the rider can be run down and run over.
The same reason a slap would hurt you. You are being "hit" by the water at a high speed.
if you were about under 12 you would get really hurt
If you mean just the club, then the putter would hurt more as it is solid, a driver is hollow. But if you meant which would hurt more if a ball was hit with these clubs and it hit you which would hurt more it would be the driver, the ball speed off a driver can easily reach 120mph.
depending on speed and form of collision...
