"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.

What's with you and this obsession with the astral plane?
Are you trying to ask me out on a date or something?
Sorry, I don't swing that way, but hey, who am I to judge, right?
