Why bother?

atmosphear commented on an entry by enisamat titled "Untitled" regarding have better posture:

Are you experiencing back pains or is there some actual reason why you would want to sit up straight?

Think of our development: we were designed to walk and run, not to sit down. Why would this so called “better posture” (which usually is to sit up straight) be better than sloughing?

If your body tells you to slough by being more comfortable position, could there actually be a point?

There was a recent study I saw in the news which confirmed my idea: we haven’t been designed to sit up straight. It’s heavier on the tail bone and muscles and 90º will reduce the blood circulation of our bottocks.

My working position is usually to have my feet on the table and my laptop actually on my thighs. I also love to lay on the sofa and do the same, and I sit most of the day without problems.
