In general I've written reviews of every book I've read since I joined GoodReads (RIP) in May 08, along with one or two I read prior to that. More recent reviews tend to be longer (sometimes a tad too long?).
I always carry a book, though I don't get as much time as I'd like to get engrossed - life is busy, but in a good way.
Too many of my favourite authors died without writing enough!
Apart from reading, and writing about reading, I enjoy Scrabble, good restaurants, woodland, and attending the theatre.
