that's true, Jibb. but in my opinion, several more serious problems emerge:

-Earth overpopulation (a stimulus to colonize the universe outside?)
-unpredictable brain reaction on vast amounts of information, collected during infinite(or excessively long) lifespan. What's the upper limit for amount of memories, or speed of learning(even if brain was being trained appropriately during lifetime)?
-huge skill and knowledge inequality between generations(probably can be fixed by 'injecting' a set of predefined facts to speed up learning and adaptation), growing generation gap.

what do you think about those?
