wooow i enjoyed every of me reading this, nice post,
what i understand about this whole science and technology scenario is that science is making the world to look old with its invention in the sense that during the latter days when science inventions were still minimum and so were the effects they call the earth a young one and we live longer in those days but with the vast technology improving standard of living making the earth a better place its like we are not enjoying the technology well enough before we die, it improves the overall earth standard and gives us the effect to die young, so sad really, people don't stay up to 70 years before they die and then during those days 150years is young.
