Live forever?

I think it would be a curse. This is because if every one were to live forever, there would be bad consequences. Either we could still reproduce, and then the earth would over populate. Then we would die. If we cant reproduce, then there would be the same people forever, and new people would never come. I think it would be only good if a few people would life forever, and everyone wouldnt know. Also if you age and live forever, that would suck.
