No 2 people smell the same

With about 400 odor receptors in the human nose, and more than 900,000 variations on the genes that build those receptors, it would appear that no two humans smell things the same way. Between any two individuals, they may vary by at least 30 percent in the population of receptors they have, according to a Duke University team led by Hiroaki Matsunami.
