Perhaps she’ll die

I swallowed a fly this morning. Things that went through my head: Gah! get it out, get it out! Too late. Now it’s going to die, struggling in the acid of my stomach. Hey, I got a calorie while running. There are those 200 calorie gel packs that some people take while running really long distances, but I’m not running that long. I wonder just how many calories was that fly? Probably a fraction of one. The energy those flies take in and burn is miniscule compared to me, but how many calories would a mass of flies equal to my weight metabolize? A lot more. But how much? First, we’d have to measure me.
