James Bond never really explains why he likes his martinis “shaken, not stirred,” so in 1999 the University of Western Ontario’s biochemistry department decided to find out.

They discovered that a shaken gin martini has stronger antioxidant properties than a stirred one — which would help Bond avoid cardiovascular disease, stroke, and cataracts.

In their writeup for the British Medical Journal, they conclude, “007’s profound state of health may be due, at least in part, to compliant bartenders.”
