" "Analog data are superior for this job because they can be changed back and forth with relative ease whenever the environment within or outside the cell demands it, and they can store an almost unlimited number of possible values, even in response to conditions that have never been encountered before.25 The unlimited number of possible values is why many audiophiles still prefer the rich sounds of analog storage systems. But even though analog devices have their advantages, they have a major disadvantage. In fact, it's the reason we've moved from analog to digital. Unlike digital, analog information degrades over time — falling victim to the conspiring forces of magnetic fields, gravity, cosmic rays, and oxygen. Worse still, information is lost as it's copied. No one was more acutely disturbed by the problem of information loss than Claude Shannon, an electrical engineer from the Massachusetts Institute of Technology (MIT) in Boston.

A study of more than 41,000 metformin users between the ages of 68 and 81 concluded that metformin reduced the likelihood of dementia, cardiovascular disease, cancer, frailty, and depression, and not by a small amount. In one group of already frail subjects, metformin use over the course of nine years reduced dementia by 4 percent, depression by 16 percent, cardiovascular disease by 19 percent, frailty by 24 percent, and cancer by 4 percent.22 In other studies, the protective power of metformin against cancer has been far greater than that.
And it is home to what is arguably the most prestigious national scientific association in the world, the Royal Society. Founded in the 1600s during the Age of Enlightenment and formerly headed by Australia's catalyst, the botanist Sir Joseph Banks, as well as such legendary minds as Sir Isaac Newton and Thomas Henry Huxley, the society's cheeky motto is a pretty good one to live by: "Nullius in Verba," it says underneath the society's coat of arms. That's Latin for "Take nobody's word for it."
