Because then I could hibernate through the winter and not have to go out in the cold! It's starting, I'm constantly walking around the house in winter saying how cold it is, dressing in a million layers, wrapping up in blankets. I'm wearing socks and slippers and my feet are still cold. And winter's not even technically here yet!
I could handle 6 months of sleep too! Yup, I think I want to go into hibernation :)
