I've mentioned before that I'm now coop appointed Board member with this coop Trust of 10 complex needs schools. Visiting them I've been struck by how much I (with a high IQ) and these kids (with a low IQ) have in common. 

Specifically we can become very frustrated when what appears obvious to us seems to be difficult for others. I'm exploring the commonalities and talking with some interesting people who research in this area. 

A friend told me recently he thought I'd do a PhD when I reach 70. Actually, it might happen sooner!
