Why do humans get "goosebumps" when they are cold, or under other circumstances?
George A.Bubenik, a physiologist and professor of zoology at the University of Guelph in Ontario, explains. Imagine swimming in a lake on a hot summer day. The water is quite warm, but the wind is strong and the moment you leave the water you feel chilly and get "goosebumps." So you change clothes and move inside to warm up. You make a nice cup of tea, get under a blanket and switch on the radio. Suddenly, you hear a song from a long time ago, the song your grandmother used to sing to you when you were a child. Again, you feel a chill on your back and again, you get goosebumps. Why do such seemingly unrelated events elicit the same body reaction?
