People drink coffee because they like the taste, but mostly it is for the jolt of caffeine that comes with each cup. It helps to keep the mind sharp during the haze of the early morning. A new study found another unique attribute of caffeine that could help lead to great future developments in medicine. They found that caffeine boosts power in aging muscles. As our bodies age, the muscles actually grow weaker, leading to increased incidences of falls and injuries. The stimulant commonly found in coffee is believed to send new power to those older muscles, leading to added strength for elderly people.
