life expectancy is unnaturally too high for our species. we were supposed to die as soon as we reach our early 20's. it was only in the last few generations that this started to change. Everything that we have after a certain age is artificial life. we were supposed to be dead, but we are not. artificial life calls for artificial happiness. everything we get in life after a certain age is already 'profit', becouse we were supposed to be dead already. its the most natural thing to get bored and depressed with life after a ceirtain age: a mature, well developed human being will enjoy every second of his existence, and thus, run out of enjoyments, since "i've been there, i've done that" http://www.youtube.com/watch?v=d9zFt6M_GLo it takes a dull, underdeveloped, insensitive human being to feel that something as mediocre as our little dull modern lifes can make us 'happy'. family, tourism, ice-cream, television, carrer... you have to be an idiot to take joy from this crap. in fact, we cease to be 'human beings' after a certain age, and become machines. artificial machines. because we were not supposed to be alive. there is nothing to look forward to. so our 'happiness' has to be artificial too. how do you create artificial happiness?
