From Dr. Mercola - 2 videos on how to live longer - the way you sit down on the floor and get up gives you the score of how long you will live, as per a study from Brazil, and the score can be reversed with the correct lifestyle changes - the other video is an exercise demonstration for those who sit all day at work or home with computers, etc.

Story at-a-glance

• How well you can sit and rise from the floor, without using assistance form your hands, knees or other body parts, may predict your risk of dying prematurely in the next six years.
• Those who scored the lowest, requiring the most assistance to sit and rise from the floor, were 6.5 times more likely to die during the study period than those who scored the highest.
• The “sitting-rising test” measures your fitness at the most basic level, testing not only muscular strength but also flexibility, balance and motor coordination. All of these attributes are essential for day-to-day living, and for maintaining your independence as you age.
• You can extend not only the quantity of your years, but also the quality, by making a few simple changes to your lifestyle, involving diet, exercise, stress reduction and more.
