A fascinating anecdote from Mark Buchanan about stress and anxiety:
“Anxiety and stress are our number one killers. I heard recently a story about Meyer Friedman, the psychologist who devised the Type A/ Type B personality profiles— where Type B is placid and limber, taking life as it comes, and Type A is two-fisted and bristling, taking life by the horns. Friedman’s initial insight that led to his personality theory came after a discussion with a chair upholsterer. The upholsterer said that most of his business came from replacing the upholstery on the chairs in cardiologists’ offices, the chairs wore first, and quickly, on the front edge. Apparently, heart patients are so impatient that, even while listening to their doctor’s life-threatening diagnosis or lifesaving prescription, they sit taut and restless, poised to flee, chafing at the delay. At the edge of their seats. The very reason their hearts are sick is written in that threadbare upholstery.”
