Brain food

30 minutes on public transport without a book is cruel and unusual punishment. I read the ads. I almost read Rebus over a shoulder. Eventually I chewed over my current preoccupation: brain food. Reading is a brain food delivery system. If junk food tastes good but has no enduring value, so too a narrow diet of fantasy fiction (or romance, or crime, or whatever your junk preference). Choose from the healthy options menu and you'll grow up big and strong. I need to balance my diet of Barbara Kingsolver (more please) and Robin Hobb (only for treats). This metaphor could go far. So if you don't read, are you starving your intellect? I'm stretching a metaphor but there may be a chicken nugget of truth in it.
