The above link is to a scientific article--the gist of it is that removing a certain gene from yeast cells increased their life span about six-fold. Scientists speculate that a similar effect could be obtained in people.
Even if you take 50 as an average life span, increasing it six times would mean living to be 300! I don't know about you, but I'd rather go to heaven than stay on earth, this "vale of tears," 6 times longer than I'd otherwise have to!
It seems that today scientists will do whatever they are able to technologically. But who's asking questions if this is a good thing or not? Is it really a good thing to artificially prolong human life by genetic manipulation? It seems to me that only people who don't believe in eternal life with God would want to do that.
Even apart from that, imagine the problems that would plague a society full of 100, 200 and even 300 year olds! Even if they managed to physically live that long, would they really have optimal health? Would it become a society with a huge overpopulation of elderly persons who need critical care, without enough younger people to provide it? Who would regulate retirement age? Would it make euthanasia compulsory? Would it create a new class of elites who could afford such technology?
What's your take on this?
