A simple balance test could reveal if you're at risk of an early grave 

Researchers believe it could be used in doctors’ surgeries as a quick way to assess elderly people.

The international group of experts from the UK, US, Australia, Finland and Brazil conducted their study with the help of 1,702 people.

At the start of the study, participants were asked to stand on one leg for ten seconds without any support, The Guardian reported.

They were told to rest their foot on the back of their leg, keep their arms straight and stare straight ahead.

One in five failed the test, having been given three attempts on either foot. Over the 12-year study period, 123 people died of various cause

Researchers made a staggering finding - that those who had been unable to balance were more likely to have died.

An inability to stand unsupported on one leg for 10 seconds was associated with an 84 per cent heightened risk of death from any cause.
