Ever since World War 1, Soldiers have been supplied with chewing gum as to improve concentration and reduce stress. Scientists are also working on a chewing gum with anti-bacterial properties, to replace oral hygiene in the field. This product is not expected to be with our troops any time soon.
A chewing gum that does exist however, is a special caffeinated gum that with each stick kept soldiers alert and awake without fatigue. Each stick of gum has about 100 mg of caffeine in it. That's more caffeine in one stick of this gum then there is an entire cup of espresso!
That's all for now! and next time, i promise to finish the history!
