"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.

OK! Meet me in Kenmore Square, Boston, Massachusetts, USA, on March 26^th at 7:00 PM! I'll be the one holding the big white sign with ":/" on it! Maybe we'll even see Cream there! But he should go back to the farm! wwwwwww
