"But everyone dies." "It's only natural to die." "What are you, nuts?!?"

These are common reactions you're likely to get when you suggest that, just maybe, people aren't necessarily going to have to die within the next century or two. Let's start by taking a hard look at the "but everyone dies" one first.

Just how much experience do we have with this obvious fact? Well, the total number of all human beings that ever lived, as it turns out, is around 107,602,707,791, give or take a few billion, according to estimates from the Population Reference Bureau, through the year 2011. World population in 2011 was 6,987,000,000 (give or take a few million). That means that about 6.5 percent of the people who ever lived are alive today.



Now the 93.5 percent who have come before us have all died after living relatively short lives, and that's a real bummer, but here are a few more reasons why your life may not have to be such a short one.
