thumbs up

the theory going around is that "sending text messages via cell phone is leading to a renaissance in the use of that original human tool, the opposable thumb. a new generation of people who are growing up using their thumbs to tap out messages on their phones' tiny keypads are now putting those handy appendages to other new uses as well. Many kids in Japan now point and ring doorbells with their thumbs instead of their index fingers..."
how ironic is that!
