Tell the guy to go and have cold shower and think about it.
If you go to motor racing, as we all do, then if you don't know it is dangerous then you are some sort of mental cripple.
Racing bikes and cars are hard things going fast, for Christ's sake you don't need a College education to know they are dangerous.
But we choose to go near them and vicariously get a thrill from that very danger. When it all goes pear shaped and we get hurt then it is very sad and everyone is sorry for you, but YOU went there and YOU took the risk so tough luck old chap. If you don't like the heat get out of the kitchen. If you go on an airplane you won't be around to claim if you have an accident. You go to races to watch other people take risks and test the limits of adhesion but YOU don't want to take any responsibility YOURSELF- get a life man!
