"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.

Now this is just plain sad...I have to laugh. XD AhHAHAHAHAHAHAHAHAA, I would tell you to an hero, but you have a weird way of making an example out of yourself. Go tell someone to an hero, then show them how. :3
