"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.

But I do sense you! You're not anywhere near me or in my mind at all! You're far away someplace! Probably on the pig farm with Cream and Shini Laser! wwwwwwww
