Oh this is such a nice comment. It's like saying People who live on the 5th floor are healthier than those on the ground.

Of course, the root cause being people who are unfit, sick or elderly cannot literally make it up a flight of stairs.

but if people aren't paying attention, like the vast majority of population dont, you'll suddenly have an explosion of condos that start from the 5th floor with the first 4 floors turned into something else.

and all of them have lifts!
