Scratch and Sniff
How often have you been somewhere, when out of the blue a scent wafts past your nasal passages and you're instantly transported back to another time, another place. I'm not suggesting that the memory will always be pleasant. Perhaps you'll get a whiff of someone's old gym shoes and you'll be reminded of Phys ed class in ninth grade when a bully made you smell his socks under the threat of a thorough pounding. Maybe it's something more pleasing, like a lady passing by on the street and you catch the slightest scent of her perfume and you're transported through time to a summer romance from your youth. In what is the first of it's kind in the world, the USPS has come out with scratch and sniff stamps. As you can see, they look like frozen treats, and actually, you don't even have to scratch them to get a whiff of the delicate sweet scent. Perhaps receiving a bill from the electric company will be a little less unpleasant with a scratch and sniff
