Do you like chewing gum? Are you aware what it does to you? Here is what I found out from one of the old magazine in the house.
There's an old riddle, "What is the difference between a gum-chewing girl and a cud-chewing cow? (The answer is:) The intelligent look on the cow's face." Well, the girl's suddenly looking pretty smart. Studies have shown that chewing gum increases blood flow to the brain, and thus made you alert. Australian researchers recently found that after 20minutes of gum chewing, alertness went up by almost 19 percent. A certain studies found out that chewing gum also lowers the levels of the stress hormone cortisol by about 16 percent.
