Sleep is elusive to me. I have had issues with it as long as I can remember. Most recently I ask the question, "Why is it the longer you sleep the harder it is to wake up?"

This is assuming of course, there is no pressure to wake up. Just on a natural basis. I think part of it is that it is just naturally harder to wake up later in the day. So the longer you sleep, the later it is in the day....?
