Did you know...

That caffeine's half-life is about 5 hours?

This means that after 5 hours, half the caffeine you consumed is still in your system, keeping you alert longer! So if you drink a cup of coffee with 200 mg of caffeine, 5 hours, later, you'll still have about 100 mg of caffeine in your system.
