#1354: LiftLess

Today’s invention is a way to improve the fitness of occupants of a skyscraper or tower block.

At, say, the seventh floor, the lift controls would only allow the lift to be called to travel to floors 9+ say and 4- to stop anyone using it to travel up or down only a small distance (buttons labelled 9,8,7,6,5 and 4 would simply be omitted or covered on that floor).

This would encourage people to make those small journeys via the stairs.

There would need to be a dedicated, keycard-access lift for disabled people in the building.
