Feet must get awfully bored. Take hands, for example. They write. They type. They twiddle. They carry things. They stuff things in mouths. They shake other hands. There's always something different going on with hands. Feet, however, are pretty much limited to two basic tasks: walking and kicking inanimate objects we stumble over. I think this is a tremendous waste of resources. Granted, feet don't quite have the manual dexterity required for tying knots and cross-stiching, but there must be all kinds of everyday activities they can perform to make them more efficient. Cars, pianos, and sewing machines have the idea, as do those trash cans where you push on the peddle to flip the lid up. But how about this? You're walking home from the grocery store with gargantuan paper bags in both arms, obscuring every part of your body from your waist to your forehead. You don't have a free hand to pull out the house keys and fiddle with the lock. But if you had pressure sensitive plates under the doormat, you could tap out an entry code with your feet, and the door would open automatically. Of course, you'd look a little silly doing a softshoe every time you wanted to get into the house, but this is the price of progress.
