If you're an older adult, having weaker hand grip compared to your weight might be a little linked to a higher chance of dying from any cause, but it doesn't add much info beyond things like blood pressure or smoking.

For middle-aged and older adults, how fast your muscles can generate power might be a better sign of how long you'll live than how strong they are — especially in men.

If middle-aged or older adults don't have much muscle power for their weight — like when pulling motions — they're much more likely to die earlier than those who are stronger, even after accounting for things like belly fat and health conditions.

How strong your hands are in your 50s and 60s mostly depends on how old you are, whether you’re male or female, how much fat you carry, and how much muscle you have in your arms and legs — not whether your parents lived to 90.

Whether you're in your 50s or 70s, having stronger hands is linked to living longer—this holds true for both younger seniors and the oldest adults.

Both men and women with stronger hand grips live longer—this link works just as well for women as it does for men.
