I guess I keep an eye on how much I sleep like most people keep an eye on their calories.
So far this week, I can say I must have got about between 6-8 hours sleep. Just for the week. That's the same as what people have for an entire night.
If it carries on like this for the rest of the week, I'd hve slept for just a little over half a day. In an entire week.
Which means, when it comes to it, I can sleep for at least 2 days.....
