How Sensitive Are You?

John D. McGervey and Bill Sones in Buffalo (N.Y.) News Magazine, quoted in Readers Digest, May 1996, p. 91.

If your senses are working normally, you can: Feel on your fingertips or face a pressure that depresses your skin a bare .00004 inch. See a small candle flame from 30 miles away on a clear, dark night. Smell one drop of perfume diffused through a three-room apartment. Taste .04 ounce of table salt dissolved in 530 quarts of water. Feel the weight of a bee's wing falling on your cheek from less than half an inch away. Distinguish among more than 300,000 different color variations. Gauge the direction of a sound's origin based on a .00003-second difference in its arrival from one ear to the other.
