This post is gross. But having just recently had my septic system pumped, and watching in some amount of horror when the guy nonchalantly said “Hmmm… the hose split” while a fair amount of “fluid” spilled onto my front yard, it got me thinking. And yes, I know it’s gross and I am sorry but I have to share this (no not really, but I think it’s funny so I’m going to anyway). So you know what you can do to save Delta a lot of money? Take a look at this fun fact from LiveScience.com:
“A healthy adult bladder can hold up to 16 ounces (2 cups) of urine comfortably, according to the National Institutes of Health.”
On average 2 cups of water weigh about 1 pound. Now I know you have likely never weighed your urine (nor have I actually) but we will use that as a comparable liquid weight. That then begs the question, what about other bits inside you? Let’s, ah hem, look at PerfectOrigins.com and then next Greatist.com:
“Depending on your height, age, and diet you could be carrying anywhere from 5 to 20 pounds of poop in your intestines.”
“…the average person poops approximately once a day—about 1 ounce of stool for each 12 pounds of her or his body weight. That means a person weighing 160 pounds produces an average of just under a pound of poop each day.”
So let’s do the icky math on the above (or below I guess). I have looked at myself, and my fellow passengers, and I think it is fair to say most weigh more than 200 pounds on average. Thus we are talking at least 1 pound of stuff inside you.
This means if we have done no “business” at all before we board a Delta flight, between urine and fecal mater, we are adding 2 pounds to the jet to haul from A-B (or in case of a mileage run C-D-E-F-G-etc) . If we, for grins, hold our nose and use a Delta 747 that holds 376 people you are potentially talking over 1/3 of a ton of extra weight on-board! (OK, that is just ewwwww)!
I could go on and show you the math of just how much fuel per pound is saved by having that much less body fluid weight on a jet but suffice to say, if you want to save Delta some money, go to the airport lavatory before you fly. Plus, it is much nicer not to have to go into those tiny (think 737-900ER) on-board bathrooms anyway right? – René
