I suspect that he was AuADHD like me. Very bright, engaged with social justice issues etc (Idi Amin was a brutal Ugandan dictator), & got into drugs of all sorts in his late teens. Personal ethics not as admirable as his broader ones - he bullied me. He managed to get his life together, qualified as a nurse, married & had 2 kids, but was awfully arrogant & life fell apart in his early 40s. Homeless on & off, neglected his health, died of bowel cancer a few years back in his early 60s. (Family history, but he took no action to monitor or his own risk.) I saw him once a few months after his marriage ended, & briefly just before he died. Did that mainly in memory of my mum. He wasn’t a nice person, but I realise that he suffered a lot & might’ve turned out so much better under different circumstances.
