My advice on posture for today: don't sit 'heavily', do not walk 'heavily'.
What I mean is: remember to Stretch the top of your head toward the ceiling. Your body wil look like it was lifted from above, your back and shoulders will appreciate that and give you some rest.
You will feel much better and look elegant aswell. Try it!
