answer:Well, it depends…for instance, I know that pouring gasoline on myself and then lighting a match is a bad idea, but I’ve never tried it (sorry for the morbid example). However, for things that are not quite so intuitive (and unsafe), sometimes you have to try for yourself. THe world’s great inventors would never have gotten any where if they had not tried things occasionally that seemed like dumb ideas… Did you have something specific in mind?
