Men who were weak as teenagers are more likely to die young than their peers who had more muscle, a new study suggests. Swedish researchers sampled more than 1 million men over the course of 24 years from adolescence to adulthood studying how their strength as teens affected their likelihood to die prematurely. Boys with stronger arms, legs and a firmer grip, for example, were 20% to 35% less likely to die from causes such as suicide or disease as young adults, they found. There was link between cancer and muscular strength, according to the study, published Tuesday in BMJ. Boys with less muscular strength were more likely to be obese or have high blood pressure as adults causes that alone signal an increased risk of death. More than 26,000 men (about 2.3%) died during the study. Suicide was the most common cause of death among the sample.
