I Need to Exercise More

So I'm going to buy this new exercise device. It's especially good for older folks like me.

It's a block of wood about 1 ft. by 1/2 ft. and an inch or so thick. It's marked EXERCISE BLOCK in big black letters. The directions for use are on it.

You place it on the floor. Then you walk around it. Then you walk around it again.

Now you can say you just walked around the block twice.
