The crunchy green releases androstenone and androstenol odour molecules into the mouth that travel to the back of the throat and then to the nose.

There’s a reason you can’t stop thinking about that special new guy or girl in your life: MRI scans have shown that falling in love sends blood rushing to the “pleasure center” areas of the brain—the same areas that are responsible for obsessive-compulsive behaviors.
