I was just noticing that very often I sit with my leg up on the desk when I type (as in working).
Weird, but oddly enough very comfortable for me! I also have a very hard time sitting with my legs down when I am watching TV or when I am a passenger in the car, I much rather have my feet up on something.
Me in my most common working position (the surgery site is healing well, by the way, still needs to be bandaged up)
Do you have any weird computer (or otherwise) habits?
