Can Your Grip Strength Really Predict Your Longevity?

Wait, grip strength might have something to do with our hearts — and brains?

Allow podcaster and author of "Genius Foods," Max Lugavere to explain.

According to him, a recent study of 140,000 people found a correlation between grip strength and a reduced risk of early death and cardiovascular disease.

"What they found [in the study]," Max explains, "was that grip strength was a predictor of long life and reduced risk of death from cardiovascular disease."

But what does this have to do with the brain? Well, Max tells us, even though this study wasn't directly related to brain health, it suggests that having a strong grip (and thus strong muscles) is good for brain health, because "what's good for the heart is good for the brain."

Max then showed us the dynamometer — a machine that, he says, measures grip strength. Rach gave it a try, and we're happy to report that her grip strength was...STRONG! You go, girl!
