Also, it would be interesting to know if you are a student or at school, or if you work. Some people work long hours so they don't have loads of time for reading.
I read about an hour to two hours a day (on average) during the week. There are days when I get home from work and head straight for my book[s] and read until midnight, but that's not the norm...or possible...the dishes don't wash themselves you know!!
Over the weekends I obviously read more, but it depends on my plans. If I stay home I'll read, on average, about 5 to 7 hours a day. More if I really like the book. It might read through the night then.
