| An almost unquenchable thirst for iced tea
The calorie-free beverage steeped from leaves is quite literally our cup of tea - or more precisely, our glass of tea. Years before trendy cafes put ice into coffee and christened it with an exotic-sounding name, there was ice tea. Today, more than eight out of every ten servings of tea we take in the U.S. are chilled. .
All cracked up: Caffeine isn't just for coffee anymore
Imagine a morning like this: You wake up, have a cup of coffee, one that's been brewed with caffeinated spring water. You eat a caffeinated doughnut, a caffeinated bagel and a large bowl of caffeinated oatmeal. In the shower you lather with caffeinated soap. You dry off, put on a pair of caffeine-infused tights, apply some caffeinated lip balm and pop a few caffeinated mints in your mouth. You're ready to face the day. And run headfirst through a concrete slab. Before you scoff at such foolery, realize that all those caffeinated products are either already available to consumers or in development. (Yes, caffeine tights are out there, promising to increase metabolism.) The days of caffeine being available only in coffee, tea, soda, energy drinks and No-Doz tablets are long gone.
