For people who ambulate easily: If you use stairs instead of an elevator (we made elevators for people in wheelchairs (or for people who have a hard time walking, or, also, for extremely heavy objects), not for over-weight people), you will not be so heavy. I don't want to offend anyone, I just hate when I can't use an elevator, because over-weight people (whose use of elevators might have led to the extra fat) take up all of the space.
