About the whole "Enzo hits as hard as a truck at 30mph" ..... assuming its a van and travelling at 30mph then hits someone, its not actually entirely illogical the force involved in Newtons psqi or pcm2 would be roughly equal to that of a a full left Enzo left hand.

Where not talk talking about the total force generated on impact (of which the truck impact would obviously have more total force in N) but N per square inch or square centimetre. Because the impact area of Enzo's hand is far far smaller in area, then on the measure of Force per square inch/centimetre then it could well be true ......... aswell as for a most heavyweights id imagine.
