Routine dental scaling

My teeth still feel uncomfortable so I thought that I would bolster my resolve by reading about how important it is to have one's teeth scaled and whatever else it is that the hygienist does. I found an evidence summary published by the British Dental Association last year whose key finding is,

No conclusions on the beneficial or adverse effects of routine scaling and polishing for periodontal health can be reached.

I am thus rethinking my previous course of spending money and time on having them make my teeth hurt.

Avoidable issues for the disabled

City center traders in Perth are having the council reduce the number of disabled parking bays. There already isn't a great abundance of them. I wonder to what extent people appreciate that for the disabled a lack of spaces on their target street could easily mean a wholly aborted trip.

I see what I think we now call little people around Dundee. What fraction do have some medical condition causing dwarfism I don't know but I imagine that even something as simple as being unusually short is more inconvenient than I realize and sometimes needlessly so. I recently saw some food and drink being offered from a high countertop and I had a vision of people having to grumpily unstrap their foldable stool from their back. I don't know what they actually do but I suspect it often tests their patience.
