It’s important to replace your running shoes every 300 to 400 miles, but getting new shoes every couple of months can get expensive. But the better you take care of your running shoes, the longer they’ll last. Although they may be your most comfortable pair of shoes, don’t wear your running shoes for anything other than running or working out. Even if you’re just walking around, you’re still wearing out the cushioning. You’re also exposing them to more sweat, dirt, bacteria and funguswith every extra hour on your feet. All of those will take a toll on the condition of the shoe upper and insole.

Summary: Regular aerobic exercise may protect the collateral circulation and lessen the severity of strokes later in life.

The network of blood vessels (collateral circulation) shrinks in number and diameter as the brain ages. Collateral circulation allows blood flow to be rerouted when arteries narrow. Using mice, researchers found that this loss of collateral vessels is prevented by exercise, according to a study presented at the American Heart Association’s International Stroke Conference 2017.
