THE PROBLEM WITH TODAY'S CROPS

This week: How man's best friend could help us live longer; the 6 indicators of good health; a new piece to the long COVID puzzle; fruits and veggies have been losing nutrients for decades; how to tell if you have seasonal depression; the right way to dispose of old medications.

PHOTOGRAPH BY BECKY HALE Could man's best friend be our best hope to reverse aging in humans? The good boy in this picture is named Ace.

What does this mean for people on plant-based diets? A LOOMING THREAT TO PUBLIC HEALTH
