What you do in midlife could reveal how long you’ll live

By closely monitoring fish throughout their lives, researchers found that simple behaviors in midlife—like movement and sleep—can predict lifespan.

Surprisingly, aging didn’t unfold smoothly but in sudden jumps between stages. The work suggests that tracking daily habits in humans could reveal early clues about how we age.

Cold weather linked to 40,000 extra heart deaths each year in the U.S.

When temperatures plunge, the risk to your heart rises dramatically. A large U.S. study shows cold weather is linked to far more cardiovascular deaths than heat, accounting for tens of thousands of extra deaths each year. Scientists found the safest temperature sits around 74°F, with danger increasing as conditions get colder—or hotter. As more people live with chronic illnesses, the threat from extreme cold may only intensify.
