My heart sank when I learned people had been poisoned with a neurological toxin. If your body doesn't die from it, it can still kill the person you were.
I'm actually really, really upset for the policeman, as I have an inkling he'll never be anything close to what he was before, and that his job was really important to him. Damage to your brain affects your ability to cope cognitively and emotionally with all your other losses, so it's multiple whammies. I spent years beating myself up for being so shit at everything and – worse – becoming a burden to other people when I used to be the one helping them.
It'll be bad for the Skripals too, of course. I just identify with the policeman because right now he's probably expecting to go back to his normal work and I know what his dawning realisation may be like.
But I do realise this is quibbling about details given the chemical attack in Syria.
