The following is a very unusual account of a true but unusual experience:
I had an arterial problem for a couple of years, which reduced blood supply to my heart and brain and depleted B vitamins from my nerves (to keep the heart in good repair). Although there is some vagueness as to the mechanisms, this made me forgetful, slow, and easily overwhelmed. In short, I felt like I was stupid compared to what I was used to, and I was.
It was frightening at first because I knew something wasn’t right but didn’t know what, and very worrying for my career because I was simply not very good any more.
However, once I got used to it and resigned myself, it was great. Even though I knew I had a worrying illness, I was happy as a pig in mud. I no longer had the arrogance of being frustrated with slow people, I abandoned many projects which reduced a lot of stress, I could enjoy films without knowing what would happen (my nickname before this used to be ‘comic book guy’ if you get the reference), and I became amazingly laid back and happy go lucky. I got on with people much better. I developed much more respect for one of my friends in particular who I always considered slow – it turned out he is much deeper than I thought, I just never had the patience to notice before. You could say I had more time to look around. The world just made more sense. The only negative, apart from struggling to perform at work, and having to write everything down, was that I no longer found sci-fi interesting – it just didn’t seem important. (I’m not joking, although it sounds like a cliché.)
