"So what are you doing to stay in shape for sailing"

First, I have my wife hit me in the face with the phone book a few times.
Then I do a couple of belly-flops off the high dive.
Next I try to grab the wire wheel on a bench grinder with both hands.
Then I finish by staring directly at the sun for about an hour.

(I should add, the phone book in step 1 is because I sail a boomless rig. For those of you with booms, substitute an aluminum baseball bat.)
