Mixed feelings on this product: On the one hand, I feel we should be exposed to a certain amount of germs, in order to keep our immune systems up to snuff. On the other hand, I've seen a child sneeze into his hand, then grab the subway pole without wiping his hand off first. I've also seen plenty of grown-ass men walking out of a public restroom without washing their hands, touching the doorknob on the way out. And that's just plain gross.
For the germophobes among you, the product in question is the Gryp Keychain. It is an admittedly clever use of materials, since silicone, which it's made of, is naturally bacteria-resistant. By simply putting it on a keychain to ensure it's always on hand, the designers have created a simple product that I think a lot of people will pony up $2.99 to buy.
