According to a 25-year study of more than 6,000 men age 45 through 68, grip strength was the best predictor of how well they’d avoid being incapacitated later in life. The weakest-gripping men suffered twice the disabilities those with hands of steel did. In a separate study of nearly 140,000 men and women, poor grip strength correlated with a higher incidence of death, especially from cardiovascular disease.

One lesson of Hamlet: Learn to weather “the slings and arrows of outrageous fortune” if you want to live to a ripe old age.

In the less resilient group, 37 percent died by that age.
Lonely people have a 14 percent greater risk of dying than the average person, twice the death risk associated with obesity. A University of North Carolina study specifically found that social isolation increases hypertension even more than diabetes does. Related research links loneliness to a weakened immune system and higher risk of heart attack, stroke, and depression. If you have social anxiety, these tips will help you calm your mind.
Older women who ate onions every day had a 5 percent greater bone density than those who ate them once a month or less, according to researchers at the Medical University of South Carolina. They also decreased their risk of a hip fracture by more than 20 percent.
