Taste is 95 percent smell. What happens when you get a cold? Can't taste anything? In talking with others about their smells, what I have discovered is that there are regional differences to our favorite smells that often depend either on our food habits or on our outdoor customs. East Coast people prefer floral scents and Northerners the smell of the seasons. Southerners seem to prefer hearty snorts of pine. Midwesterners like the whiff of hay and farm animals. Westerners like the aroma of barbecuing meat.

Whatever our pet smell, huge histories of time are relived within the microseconds of a sniff. Nothing can bring back a time, a place, or an emotion better than an aroma.
