ah yes trippong is dangerous I once had a friend that tripped so hard that all of his bones were fractured into dust and he was turened into meat past and that was all in just tripping on a cement sidewalk.
I do wonder, people always use the 'I tripped' to cover up, but with the strength alot of the people in novels have, often stronger than their defenses mind you, wouldn't tripping full speed really **** them up?
