New research out today from neurobiologists at Duke University helps uncover why something that smells great to one person can smell horrible to another. It’s all down to our genes.

The researchers say that there are over 400 genes coding for the olfactory receptors and there are over 900,000 variations of these genes. These receptors help to control how we perceive a given smell, whether it be good or bad.

So, next time you sniff a gorgeously aromatic flower and your friend says it smells like garbage, just remember it’s all in their genes.

genetic differences in our olfactory receptors means what smells good to one might smell bad to another.
