TOTAL human extinction.... 2099!!!!!?

Certainly possible but idk. after all we survived corsets and lead base makeup, to mention a few. I worry more about the coming climate changes. But the guy who responded to your ergo does make me worry about our intelligence level. Guess basic reading is not one of his talents. Of course commas and other grammar are not really part of texting soooo.... It might just be a race as to which of our many crazy habits will do us in. Maybe a comet will save us the agony you speak of. But then again maybe we'll wake up and stop being as short sighted as some of your responders. Or maybe the remaining percentage will inherit a better world more able to heal itself after the numb portion of our population finishes it's blythe path to extinction. We may never know. But I still have hope!
