that's mostly because of child death bringing down the average. The average age of someone who lived to be 20 went up to like 65.
Well I know that they military will definitely have lasers by then, even some type of force field for fighter jets (I saw it on the Discovery Channel I think, it is amazing...). Flying Cars, Elevators to space, unmanned military fighters with humans only used in limited scenarios to secure things, and their military suits will be insane (already halfway developed and they are SICK). Can't wait. But I mainly wanted to say... Ronan, your sig is absolutely epic. I laughed my ass off.
