I don't have an appointment with the hairdresser for the next two weeks, but already got something to read during my next hair treatment

😄

not even extroversion escaped- which genetic variation correlates with ADHD

I knew it!! This is very cool! The evidence against them is amassing! :D

It is now understood for example, that we become more agreeable as we age, and less Open to Experience as the years go by

To play devil's advocate, I could say that perhaps the change is also genetically mediated: just like hair changes to white as we age, maybe we're meant to be more agreeable as we age because we're not as strong, say, or because there's more progeny to take care of and tolerate.

Thanks for your (as always) detailed and informed reply!
