Are standing desks last year's advice? Whatever. Unless you're lucky enough to be on your feet all day for work, you probably sit too much. We all do. When we go home, we sit on the couch. When we have dinner, we sit on a chair. When we watch a movie, we sit in the theater. When we go out, we sit on a stool. Our life is filled with sitting interrupted by little moments of walking so it's important to, well, be good at sitting. This animation video shows you the correct posture. [Flikli via Laughing Squid]
