YES alex! its something that we all so naturally do as modern humans, hunching, slouching,! I always keep telling myself to sit straighter and pull my shoulders down and back. I first became aware of it through practicing yoga and noticed a significant difference when I started training my posture, your back becomes stronger and its easier to do. IT can hurt alot of ppl at first! I know some ppl who CANT do it... or unwilling to try slowly because they dont have the patience. For me its a necessity because i have a lot of pain and inflammation from bad posture, it makes me lazier and more lethargic! I've never seen this brace thing but looks good, we used to do something with a rubber string thing but not quite like that. Your house look so cosy btw but for some reason ur were so quiet on my computer!
