Johnny Be Good (1988)
Thing is, I know my gut flora are benign, but how does my immune system know that? This is an organ that occasionally freaks out and kills people because they ate a peanut, which is sort of like burning your house down because you saw a bit of fuzz that looked like a spider. We can probably assume it’s not into subtle distinctions.
Why doesn’t your immune system kill your intestinal bacteria?
I’m watching this PBS special thing on brain surgery. To make sure they’re not cutting out anything the patient will need later, they have a little tool and they poke at the brain and see what happens. If a finger twitches or something, they know that bit is important and should be left alone. So I called my parents and told them if I ever need brain surgery, I want them to film it so when it’s over I can watch the doctors play with my brain.
