The other day I was entering a building at my university. Naturally, there was a door in the way. I consider myself well-educated, and don't have too much trouble opening doors. If it's tricky, you can try various twist/turn and push/pull combinations. It's not rocket science.

What did I see next to door as I approached? C'mon, guess.

I saw a sign with instructions on how to open the door.

Push button, pull handle.

What the?!?! Someone explain this! This is a university! I can only wonder what kind of people are they letting in here.

My faith in humanity is gone...

this reminds me of the signs in some of the harvard lecture halls.. the signs that say 'do not write on walls.' i guess the students go there to become smart, not because they're smart already..

How to open a door in two easy steps: Build up speed. Hit it.

When opening door a door this way, you should try to hit with three points of your body at the same time to reduce the impact shock: the side of your thigh, the side of your hip and the back of your shoulder.

This allows you to open a range of different doors without severe bodily harm. Unfortunately it is impossible to say generally if the lock or the hinges will give in first.

Wait, you wanted to open an unlocked door? Never mind.
