Cosmologically speaking, humans and all other animal forms of life (here on Earth) don't live very long. We can thank this fact for the evolutionary design of life based on the 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 millennia, the life span of humans today, enhanced by miracles of modern ways of living, which, in short, 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 the entire population) of ancient times was way shorter than today, but this statistical data was misleading for the fact of the vast number of people in the distant past who died very young due to high c...
