The probability of me leaving pan on high heat by accident: high, done this multiple times. The probability of me reporting any sickness as teflon flu: zero because I had no idea that Teflon could cause anything like this until yesterday when I looked this up.

And we don't know anything about long-term effects.

Anyway it's pointless because no matter how safe teflon is the side products of its manufacturing should already be enough of concern to render it illegal but somehow no one cares
