Humans, especially in some places, are living longer. We may have learned that reaching the age of 80 years was surprising but these days, it is getting more common. Drugs and antibiotics certainly matter but even more so, is hand-washing with soap and clean drinking water. See the book by Steven Johnson called "Extra Life", about increasing longevity. See the book "The Longevity Economy" by Joseph Coughlin and the book "The Longevity Project" by Friedman and Martin. Also, see "Extra Life" on PBS. So, a bar of soap is an advanced scientific tool and so is a glass of clean water.
