"laziness"

Hello /sci/,
Could you explain to me why people are willing to go out of their way "to be lazy".
Examples:
  Walking an extra 20 feet to the automatic door instead of pushing open the other door.
  Waiting an additional 5 minutes instead of going up a flight of stairs.
I'm sure you've observed others. Is it just a habit people get into? Has there ever been a study into this.

Ah...the truth finally comes out! Plus you live in Canada? That narrows it down inside the entirety of the universe. I'll be seeing you very shortly. Woops! I'm already there...inside your ego-castle...and I'm done fucking up your shit...your shit is fucked up enough. TTFN! :3
