That's better! Posture people. It's important. It makes you look sooo much better.
I forget sometimes too, then I see someone all hunched over with rounded shoulders and I quickly correct myself. When I lived at home, my mum would often remind me, and the little motto has stuck with me as I've grown older.
I'm often appalled at the number of people I see out and about, with awful posture and slack stomachs. Young, old, fat, fit, thin, average... Pull it in!!! People do notice. I notice.
