A little-known fact: Next to nothing is impossible. Actually, nothing itself is impossible. Nothing is the absence of all things. But that absence is, itself, a thing, and—well, the logic’s so screwy you could uncork a wine bottle with it.
The point is, most of the stuff people say is impossible is not at all impossible. Starting a car that’s already started, that’s im- possible. Traveling to where you are is impossible. Sleeping through Rick Astley’s “Never Gonna Give You Up” is impossible (and so is listening to it).
And that’s the list. Taking a neon-blue dump? Well... You’d think, but really it’s just improbable.
To sum up a wildly unmanageable concept: most things we call impossible are actually just things that require more effort than we’re willing to give. And even when it comes to impossible, it’s really only the Rick Astley that nobody will try if they’re given a few slices of pizza.
