Between a teacher and two students after their first yoga class....
Teacher: How do you feel, did you enjoy that?
Student 1: Yes! I feel good. I'm always interested in trying things that make me feel good.
Student 2: I really enjoyed lying on the floor. I'd forgotten how good lying on the floor feels.
Teacher: Yeh? So simple!
Student 1: Lying on the floor is good for you. I slept on the floor my whole life in Africa, and I come to Europe and start sleeping in a bed and now I have aches and pains everywhere when I wake up. I never had those pains from sleeping on the floor. It's like a massage while you sleep.
