Adults who have difficulty sitting and getting up off the floor may be at risk for early death, according to new study by researchers in Brazil.

In the study, researchers rated the ability of more than 2,000 adults aged 51 to 80 on how easy it was for them to sit and then rise from the floor. The researchers used a 0 to 5 scale for each participant and deducted one point for each time the participant had to use support to assist them, such as a hand or a knee.
