Sorry I took so long to reply! I'm still not used to Lemmy. :P

That was an excellent answer. I imagine it's further compounded by how kids are sorted into grades, with someone being born very late to the grade's cut-off having a disadvantage to someone born many months earlier/at the start of the cut-off.

From what you wrote, I'm almost persuaded to think that it's something kids should be taught in school, but far later. I'm back on the boat of having calligraphy classes offered in high school as electives. The trouble is, once I suggest that, I feel like it's setting myself up to be argued into having it at a much younger age and as a mandatory part of education, which puts us right back into the problems you listed out. :(
