Royal Society of London for Improving Natural Knowledge. More simply known as the Royal Society, the world's oldest national scientific organization was established in 1660 to promote and disseminate "new science" by big thinkers of the day such as Sir Francis Bacon, the Enlightenment's promulgator of "the prolongation of life.

Here's the important point: there are plenty of stressors that will activate longevity genes without damaging the cell, including certain types of exercise, intermittent fasting, low-protein diets, and exposure to hot and cold temperatures (I discuss this in chapter 4). That's called hormesis.28 Hormesis is generally good for organisms, especially when it can be induced without causing any lasting damage. When hormesis happens, all is well. And, in fact, all is better than well, because the little bit of stress that occurs when the genes are activated prompts the rest of the system to hunker down, to conserve, to survive a little longer. That's the start of longevity.

Today, I can read an entire human genome of 25,000 genes in a few days for less than a hundred dollars on a candy bar–sized DNA sequencer called a MinION that I plug into my laptop. And that's for a fairly complete readout of a human genome, plus the DNA methyl marks that tell you your biological age.
