Cosmologically speaking, humans and all other animal forms of life (here on Earth) don't live very long. We can thank for this fact to the evolutionary design of life based on organic chemistry we are all made of. We came a long way from the point in history when evolution started to boost our development from hunter-gatherers into today's dominant species. But do we live longer today than before? Despite common belief and compared to our ancestors who lived in the past dozen of millenniums, the life span of humans today, enhanced by miracles of modern ways of living which in short list include improved health care and nutrition, better sanitation, access to clean running water and immunization, is not dramatically extended, if at all. Yes, the life expectancy (average life span of entire population) of the ancient times was way shorter than today but this statistical data was misleading for the fact of the vast number of people in distant past who died very young due to high c...
