We expect a lot from our cell phones. Not only do we use them to make and receive calls on the go, but we rely on our cells for texting, accessing e-mail, listening to music, snapping pictures, recording video, playing games -- the list could go on and on. But as amazing as these devices are, they're not invincible. Certain tasks, such as watching a movie or roaming out of network, eat up lots more of your phone's battery than other activities. If you're not careful, you'll end up with a dead phone and no charger.
Our bodies are no different, because we expect a lot from them as well. Each day, we're responsible for different functions, just like our phones.
