What about the calories used to travel up and down the stairs by multiple family members?

Say over a month you burn enough calories to eat an extra steak to make up the energy lost, would the environment be better or worse off?

What about time lost? Say you wasted an extra hour or two every fortnight just getting to and from the fridge, what if instead you had read a book or worked on your hobbies? Would you be happier? Would your family be happier having an extra hour of time every fortnight?
