Google vs. Death
There is something very weird about people routinely speaking of immortality as something that is actually a thing. For all we know, stars die eventually, the sun will burn out eventually, the universe as we know most likely comes to an end and so forth, you can not cheat basic physics. To me this is the same kind of refusal that makes some people believe in god, and that shows how hopelessly biased we get on topics we are emotionally involved in. On any other topic with the information available everyone sane would asses the likelihood of success as maybe less than 0.001%, but if you ask about this specific thing, it's more like 50%...(Speaking in advance: I understand this is in fact about life extension)
