[fausto]

I don't know. My last block was probably ten years ago. What happens though is that I do slow down my reading, I read less. But then again, last time was when I was a student too busy drinking, chatting up, going to gigs, etc. Over 4 years ago now, and I kept on reading -- never leaving a book unfinished or any gap between one ending and getting started on a new one, even then.
The only book I didn't finish in the last few years was by Pierre Guyotat.
