Some of us have grandparents who had to use an outhouse. Now we have electric cars and lazers, and showers that give you a tan as you bath. And you're worried about getting bored if you live too long?? Really??! Live a few lifetimes and see how much life changes.
Point: immortality
However, given the current rate of governmental interference, and the leaps we're taking in identity reading (my eyes and fingers were scanned before i could work)changing one's identity to hide the fact that you're 500 years old may become imperceivably difficult. They will find you, detain you for identity fraud, and then you will belong to some governmental lab which will hold you and study you in the interest of "national security" you freak.
Point: invincibility
In my lifetime I have been discusted by the direction of society as a whole and the effect we're having. Things that I was fond of destroyed and replaced with more concrete -more garbage -and more government. Do you Really want to see the planet further destroyed; cultures further disgraced? And people don't evolve, they deteriorate. A person certainly would not evolve -so much for that arguement. And you want to be a historian?? what happened when you were 4? do you remember?? try remembering 50 when you're 1,000!
Point: invincibility
So you want to be a super soldier?? use the government grants for college and whatever pay the army gives?? Is that the sum of your immagination??? How about take a few years to get in top fitness and become a fighting champion a la boxing, wrestling, ultimate fighting.. after a few years of going undefeated, declare yourself undefetable; take your millions in payment, trophies, and Endorsements, build a house on a private mountain; retire with your family and live the remainder of your days in luxurious comfort and adventure.
Point and Mark: INVINCIBILITY!
