Sometimes at night, when I go to bed, I like to do a bit of reading. It helps me get to sleep, but more often than not it causes me to stay up a lot later reading when it’s a really good book.
Lately it’s been one of the two times I have available to do any offline reading.
Got a new book by Larry Niven, so I guess I’ll be up a while. But again, who needs sleep anyway?
