You and OP appear to agree there is a significant problem, you just disagree where the "blame" lies.
OP suggests the built environment is insufficient. You baselessly assume OP must have a serious medical issue as, apparently, you can't imagine that the built environment is really the appropriate villain to finger in this case.
Before anyone jumps up to accuse me of nefarious intent and of being secretly on the side of "America's built environment could stand to be improved" I'll just openly admit that's exactly where I stand and save you a bit of furious typing.
