There are so many laws and safeties, that it seems nearly impossible to have an accident. The problem though, is that we need accidents, and lots of them.
Danger is nature's way of eliminating stupid people. Without safety, stupid people die in accidents. Since the dead don't reproduce, our species effectively becomes more intelligent (or at least, less stupid).
With safety in place, no matter how well intentioned it may be, we are devolving into half-witted mutants, because idiots (who by all rights should be dead) are freed to go out and breed even more imbeciles.
Let's do away with safety and improve our species. Run with scissors; play with blasting caps; jaywalk; go swimming after a very large meal; stick something in your ear. Do all of these things and do them with gusto;
Future generations will thank you!
Personal note: This entire commentary is an excellent argument against the validity of the Theory of Evolution. Were the Theory of Evolution correct, then humankind would not tend to build societal systems that override evolutionary tendancies...
