Lay down flat on your back. Now stand up. If that was easy, congrats! Give yourself a pat on the back.
If that was difficult…well… you might die sooner than you’d like. At least according to some studies.
Don’t believe me? There’s lots of studies (sit to stand studies, I lay down in the video) that say otherwise, like this one.
Try this simple test. Where do you stand (pun fully intended) on the level of difficulty?
