Reader Dan Rothman sent this in. If you’re worried about contracting the flu, you might want to check out the Touch-Stick. It’s an ABS plastic key shaped tool that you can attach to your keychain. It has a flat surface that you can use to press buttons at the ATM, gas station or elevator. It also has a pointed tip that can be used like a stylus on other surfaces. I would rather just use my fingers and then lick them, because I’m tough. If you think the Touch-Stick is the way to go, you can get one for $2.99.
