Interesting. I have a theory about pens. Houses absorb pens. If you buy 4 pens, the house can easily absorb them in a few days or a week. You have to supersaturate the house. 15-20 pens. The house can absorb most of them but not all - so you will always have a few available for a while.

Maybe reading glasses are the same.

I know the feeling. I suddenly realised I.need glasses when I was doing jewellery and I couldn’t see the links in the chain<

It's hell to get old. I wouldn't know a thing about that though.
