why do we fall down the stairs? Stairs are made for ascending, they were a good idea back in the old days but today they could use improvement. Truth is, the stairs are wide enough for the ball of the foot to safely fit, but coming down there is not enough space for the ball of the foot to fit. When you consider the fact that older folk have weak knees, ankles, any shift in the center of gravity will manifest as a fall.
So what to do, fortunately there is a system of ropes and pulleys that could easily be converted as a lift. A crank and some gears would make it easier for people to use it manually. We can afford it, we spend millions in hospitalization, broken femurs, hip replacement. xrays, MRIs.
