Why do you want to delete it? quote:
If we can't survive without all this technology, how the fuck did people survive without it ? Not very well. Longevity has increased over the years. Evidence-based studies indicate that longevity is based on two major factors, genetics and lifestyle choices.[5] Twin studies have estimated that approximately 20-30% of an individual’s lifespan is related to genetics, the rest is due to individual behaviors and environmental factors which can be modified.[6]In addition, it found that lifestyle plays almost no factor in health and longevity after the age of 80, and that almost everything in advanced age is due to genetic factors. In preindustrial times, deaths at young and middle age were common, and lifespans over 70 years were comparatively rare. This is not due to genetics, but because of environmental factors such as disease, accidents, and malnutrition, especially since the former were not generally treatable with pre-20th century medicine. Deaths from childbirth were common in women, and many children did not live past infancy. In addition, most people who did attain old age were likely to die quickly from the above-mentioned untreatable health problems. Despite this, we do find numerous examples of pre-20th century individuals attaining lifespans of 75 years or greater, including Benjamin Franklin, Thomas Jefferson, John Adams, Cato the Elder, Thomas Hobbes, and Michaelangelo. http://en.wikipedia.org/wiki/Longevity#Present_life_expectancy
