In reality, we are empty space, pure energy!
We have to eat each other to keep this energy going!

If we were, we would, like the photons, have no mass and then we'd
have to move at light speed all the time to avoid vanishing. But
those 0,0000000000001 % of us not being empty space contains all of
our mass and enable us to calm down so we don't have to run like
light...
