Pedro On Riding Ghetto Elevators

Ghetto elevators, I hate 'em. I'm talking about the one's with an inch of either green or dark blue paint on the doors, the one's that drop half a foot before they go up. Or when they stop. The one's that are too small for a stretcher even after you fold it like a Transformer.

Ghetto elevators also shudder when they move, have lights that flicker and the cars smell like piss, pot and burning machine oil.

Whenever possible I will take the stairs. I usually arrive on the floor long before the Ghetto elevator. Even when carrying the House bag, even when the landings are filled with Gangstas.

Here is a little known fact about elevators you might not be aware of. Not just Ghetto elevators, all elevators. Store this little factoid away in the back of your mind if you are afraid of elevators:

Once the door of the elevator closes there is less than five minutes of air inside the car. Five minutes. Less if it's crowded. Just five minutes of air.

Actually, the urine on the floor and caked dust on the inner gate door, combined with the single bare CFL bulb (really? We're getting environmentally conscious here?) can add hours of survivable air.

I too take the stairs. Did we work together last week?

Using stairs is good for health & fore mind also.

Five minutes? Hrmm, that seems a bit fictional. Lets do the math.

Lets say we have a tiny ghetto elevator that is 1x1 meter wide and 2 meters tall giving us 2 cubic meters. This gives us 2000 liters of volume(metric volume measurements are based on cubic length measurements, think cc/ml).

If you are a really hefty person you might displace 200 liters of that air by being in the elevator. That leaves us 1800 liters of air. With an average tidal volume of 500ml and a nearly tachypnic rate of 20 a minute we breath 10 liters a minute. That means it would take 180 minutes to breath all the air one time and that only reduces oxygen from the ambient 21% to 16%.

I am not sure how many times you can rebreath the same air until rising CO2 and and dropping O2 levels become a serious problem but I would bet that it is more than twice. So that puts us closer to 6 hours.

I guess this just proves that 73.63% of statistics are made up on the spot.
