"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.

why don't you meat me IRL, and you'll find out for certain. Or, just express what this entire thread is exemplary of, "Laziness".

Surely you didn't assume you were exempt from such human trifles? Hmm....
