How come you press harder on a remote control when you know the battery is dead?
Same reason we keep pushing the elevator button, even tho the light is already on, and we know that pushing the button again won't change anything!
Same reason we holler at people on TV.
Just the stupid way the human mind works. The human mind inherently applies force as the primary solution to a problem.
For the same reason you push harder on the fuel petal of a governed vehicle!.....................Wishful thinking!
Because it works duh
