The chances of having a heart attack, stroke or dying young may be hidden in the palm of the hand, a study suggests.
A trial on nearly 140,000 people in 14 countries, published in the Lancet, suggests grip strength is better than blood pressure at predicting risk. The international research team said it would be a "simple, inexpensive" tool for doctors. Experts argued the link between grip and the heart was unclear and needed more study.
The maximum crushing force you can exert in your grip naturally declines with age. But those whose grip strength declines fastest may be at greater risk of health problems, the study suggests.
