The Sniff to Feel Happy

Are you feeling down?  Sniffing the sweet and tart aroma of green apples  is an easy way to bring the smiles.  But the scent doesn't always have to come from fresh apples.  Slathering on some apple-scented lotion will do.  According to experts, the delicious scent will stimulate pleasure receptors in the brain and spur the production of the feel-good hormone serotonin.
