CLEVELAND -- A new study released Thursday claims to predict longevity by how easy or difficult it is for you to sit and stand, without using your hands or knees.

The study found middle-aged and elderly people who needed to use both hands and knees to get up or down were almost seven times more likely to die within six years, compared to those who could spring up and down without support.

The study done by Brazilian researchers looked at 2002 adults over a period of more than six years. The participants were ages 51 to 80. During the study 159 people died. Researchers said the majority of the deaths were people who had the most trouble getting up or down.

So, anchors Chris Tye and Erin Kennedy decided to try and get up and down without using their hands or knees. It is not as easy as it sounds they found out.
