Average healthy adult breathes 12-20 times a minute (those are the numbers we carry around with us in healthcare). So at the upper end, 20b/minx60min/hrx24hr/day gives you $1,440.00 a day. If we count even the impact of your foot while running as steps (does a specific word for that exist? I don't know. In my head a step comes from walking...), a good pace is 3 steps / second. Go for a good 30 minute run, and you get 3st/sec * 60sec/min * 30min for a whopping total of 5400 steps, or $1,350.00. Move around your house while cooking, cleaning, getting the kids/pets/lover where they need to be, and you might end up a bit better off than the breathing. My average steps just around the house add up to 5k-6k, I believe.

The IRS can lick my balls if I'm being paid in cash under the table though.
