I totally support Rich - time try your two finger test with a capacitor charged to 20 Joules! It is NOT unpleasant - it Hurts like Hell.
In the 80's we had a 'strange' engineer in our lab that left 2.2 ?F capacitors charges to 300V laying about - until someone grabbed him by the throat! The limit is to prevent death and serious injury. It will not prevent ALL deaths but a 'reasonable' percentage of the normal population. In the same way there are limits set on how many passages an aircraft designer can kill per 1,000,000,000,000 hours of flying.
