Self-control need a boost? Gargle sugar water, researchers say

(But I wonder if they controlled for whatever amounts of sugar subjects might inadvertently get in them anyway while gargling)

"Researchers used to think you had to drink the glucose and get it into your body to give you the energy to [have] self control," says coauthor Leonard Martin, professor of psychology. "After this trial, it seems that glucose stimulates the simple carbohydrate sensors on the tongue." He adds: "This, in turn, signals the motivational centers of the brain where our self-related goals are represented." And it's these signals, he adds, that wake your body up and tell it to start paying attention.
