I consider sleeping a hobby.
Some people like to do it more than other and some don't like it all.
There are sooo many other exciting things I could be doing or learning. Sleep is at the bottom of the list of things that I want to do in my life.
Statistically, people will sleep one-third of their life away. I really would like 20-40 years extra to life the way I choose.
But, I guess science (and my body) says I have to...

ps - For now, I guess I could also just call it "meditating all night". It is possible to figure out problems and solutions when lying on a bed.
