It's a test called ‘Sit and stand up.’ In this test, you need to stand, cross your feet so that your feet remain one next to the other and slowly lower and sit on the floor, without any help from your hands or knees. Then you need to stand up with your legs still crossed, again without help. If you sit down and stand up without using hands or losing balance, then you get a perfect ten, and you will live as long as your life expectancy is genetically predicted.
However, for each help from hands, moving your shoulders or knees, you lose points, and if you lose your balance, you lose half a point. The test shows the state of health of the entire organism, and experts point out that people with test result 3 and less are at risk of death five times more in the next five years.
