I find this to be very interesting, but before that: 1) The test is aimed at older individuals (50 and older), so no, toddlers are not expected to pass it 2) This is a pop-sci article after another article; the paper is here: https://bjsm.bmj.com/content/early/2022/06/22/bjsports-2021-105360 https://bjsm.bmj.com/content/early/2022/06/22/bjsports-2021-... I find it very interesting as balancing on one leg logically is a full-body exercise, and thus doesn't look suspicious as a _general proxy_ of overall health. Also, this test does not require anything but willingness of the testee. Next it's about negative feedback - standing on one leg for 10 seconds doesn't mean longer live (the linked article title is, of course, poor); and failing the test is also not a "death sentence", but rather a very clear and simple sign to the testee that "you should be exercising more, ya know". Passing this around my elderly. And no, I won't be recommending buying anything.
