When I actually had a bath tub (*tear*) I used to love sitting in it (with water obviously) and reading until I dosed off. But then I noticed that I always got tired in the bath and I put two and two together and realized that it was the way my neck was being contorted when sitting back was kinda like a very mild sleeper hold. So the question is was I getting sleepy because my brain was being deprived of oxygen and was I potentially leaving myself open to brain damage? P.S. I just realized I posted this in the wrong forum. If a mod could move it to general discussion that'd be great.
