People are clueless on a whole lot of things, I think is the safe assumption! Seems to be quite a bit of "knowledge" that gets out there, that folks take as the gospel truth once it has been heard.

Even in your situation, what sense would it make to ask if you have knee pain? The logical person would assume if you did, you would change the situation causing it, not just suffer through because you loved platforms so likely there was no issue.
