I get it—a baby bottle with a built-in UV lamp for killing any germs that might be lurking in the formula. Parents would eat this up. But would it do more harm than good?

Seriously, we have become a generation of germaphobes with our Purell bottles and crazy germ-killing gadgets. We are never exposed to germs so our resistance is down. That's probably why everyone always seems to have a cold. So ditch the UV lamps, go out and and push that cart at Walmart around to toughen up. [Yanko]
