Our happy hour fact to amaze you drinking buddies with.

Overweight and obese people are more sensitive to the smell of food.

Researchers at the University of Portsmouth tested 64 men and women on their sensitivity to food odors by having them smell cooking herbs of decreasing potency until they could no longer pick up the scent. It turned out that overweight or obese men and women were able to detect the herb smell for about 20 percent longer than those with healthy body-mass indices.

"It could be speculated that for those with a propensity to gain weight, their higher sense of smell for food-related odors might actually play a more active role in food intake," said Lorenzo Stafford, who headed the study. Stafford hopes his research will lead to solutions for those who struggle with their weight.

Before that happens, we should probably try to figure out a way to harness fat folks' heightened sense of smell in search and rescue missions.
