A third option is leaning back in your chair. I find that I never get tired of sitting in this position.

Yeah, but you have to curve your neck forward, which seems to cause it to bear the weight of your head on a curved portion of the spine rather than a stacked one.

How old are you? I'm curious because I used to be like that. Now, my back hurts if I am anything but sitting upright or laying flat.

After several years, my chair has gotten tired of me sitting in this position, and it's no longer usable when I want to sit up and get a closer view of the screen. One of many reasons I'm planning on throwing it away when I move out.
