"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.

Hold it there Kodak! Astral projection can sense your presence on all frequencies, and you ain't there! You're refusing to suggest an new place to meet! Are you an coward! You talk though online, but you probably are not so though IRL! If you still refuse to suggest an new place, then I'll see you Friday! If you refuse to show then that will tell me that you are truly an coward!
