Dates are often approximate and change as more research is done, reported and seen. Older examples of any given technology are often found. The locations listed are for the site where the earliest solid evidence has been found, but especially for the earlier inventions, there is little certainty how close that may be to where the invention took ...
Stretching is a form of physical exercise in which a specific muscle or tendon (or muscle group) is deliberately expanded and flexed in order to improve the muscle's ...
Driven by a pervading assumption that flexibility is the ultimate measure of joint health — and because stretching tends to feel good and takes relatively little effort — people frequently ...
A calendar date is a reference to a particular day, represented within a calendar system, enabling a specific day to be unambiguously identified.

A 2021 study found that one extra year of life expectancy due to slowed aging equates to $38 trillion in economic gain. The goal of the competition is to extend health span, the number of years ...
