Ooooh, can we do truth tables?

I can see it now...."today class, we shall learn the contrapositive"...... B)
"Champions aren't made in gyms, champions are made from something they have deep inside them - a desire, a dream, a vision. They have to have last-minute stamina, they have to be a little faster, they have to have the skill and the will. But the will must be stronger than the skill. " - M. Ali

I've heard of people swallowing DDT by the spoonfuls with no ill effect in the short or long term.

100% of people who ate DDT were no longer able to lay eggs.

I'm not sure where you got the idea that direct harm to humans was why DDT was banned. It was banned because it tended to prevent animals from laying viable eggs, which nearly wiped out a number of species, including the bald eagle and some kinds of fish. It was banned in 1971, and classified as a possible human carcinogen in 1985.

If somebody told you that it was banned becuase it caused cancer in humans, they were at best misguided.

almost, al... a tautology is actually based on truth... an example would be, global warming is either true or not true

My mistake.....or perhaps ours....Tautology refers to the repetitive use of different versions of the same situation to demonstrate proof of validity. For me, only people espousing false premises need to use tautology in an attempt to validate the correctness of their position.
