Mandy Oaklander | September 30, 2026     Want to protect your body as you age? Focus on preventing frailty, which is an actual medical condition that puts you at higher risk for falls and complications after surgeries. One of the best ways to do that is with exercise—but not any old kind. In a clever new study out today, which my colleague Veronique Greenwood wrote about, researchers coached retirement-home residents to walk down the hallways at different speeds. One group fared far better than the other. Read on to find out how to apply these findings to your own stroll. TODAY’S TOPICS Learn from your local landfill What to say when your child criticizes their body Is “bricking” worth the hype? The walking-speed test to try The brain-injury risks of roller coasters         QUICK CHAT Take a trash tour While reporting a story about cutting down on school-lunch waste, I met Lauren Click, who runs a nonprofit that teaches kids about composting. Click has been to a lot of landfills. (Her boyfriend has also, apparently, heard quite enough about compost.) Somewhere along the way, she convinced me that the rest of us should visit one, too. —Angela Haupt, Editor, Health & Wellness This interview has been condensed and edited for clarity. nikom khotjan—Getty Images You really think families should take a field trip to a landfill? Absolutely. A lot of landfills give free tours, and kids are fascinated. Trash day is already a big deal for a lot of kids, and at a landfill there are huge trucks and all this equipment. They give them little hard hats and vests. There’s a lot to see.  What do adults notice? I think the adults have a different reaction. You start seeing labels on the ground and birds eating trash. You see the impact the landfill has on the land around it. A lot of us are disconnected from our waste systems—we think our trash goes to some magical faraway place. But the landfill might be 20 minutes from your house. Does seeing it actually change the way you think about throwing things away? It confronts you with the reality that you contribute to this. Instead of looking at a picture in a textbook, you’re seeing where all this stuff actually goes. These systems aren’t far away or made up or magical. Any other field trips for people who suddenly find trash fascinating? Recycling centers are fun, too! They have really cool technology now that sorts paper, cardboard, metal, and other materials. I do this full-time, though, so I probably have a different definition of the word “fun.”          SPONSORED Your K-Cups Sat in a Warehouse for Months Grocery store pods spend months going factory → warehouse → truck → shelf, losing the flavor oils that make coffee taste like coffee.

The goal is to keep the door open. Experts recommend trying these approaches instead. “Tell me more about that.” Find out what’s underneath the comment. Did someone say something cruel? Are they comparing themselves with influencers online—or worried they won’t fit in? Try: “I can see why that was upsetting.” You can validate the hurt without agreeing with the harsh judgment they’re making about themselves. “What did your body do today?” Shift the focus from appearance to experience: Did they walk the dog, laugh with a friend, or score a goal at soccer practice? Remind them that they don’t have to love how they look every minute—but they should treat their body with respect. And watch what you say about your own appearance. No script about body confidence will overpower the criticism your child hears you direct at yourself. —A.H. Read the full story here.         WORTH THE HYPE? Can a Brick break your scroll? FreshSplash/Getty Images Want to spend less time on your phone, but keep ending up on Instagram? The “bricking” trend puts an obstacle in your way: a small physical device, such as the magnetic Brick tile, that blocks selected apps. The idea is to leave the tile in another room while keeping your phone with you. To restore access, you have to bring your phone back and tap it against the tile. Unlike screen-time limits you can dismiss with a tap, “you have to get up, walk somewhere, and make a choice with your whole body,” says Elizabeth Bodett Dresser, a licensed clinical professional counselor in Chicago. The verdict: Worth trying if you keep overriding limits—but first, try the free option of leaving your phone in another room. —A.H.          SPONSORED 1,000+ Claude Prompts Top Professionals Actually Use at Work Claude can be your analyst, editor, and strategist.

But how can you tell you’re strolling quickly enough? Here’s what I learned from the paper: You’ll be working very hard, but not so hard that you'll need to stop imminently. You should be breathing hard, and while you might be able to exchange some words with a walking partner, you won’t be able to maintain a conversation easily. —V.G.         WHAT WE’RE READING Now that children are back in school, we must use the tools we know work to keep measles out of the classroom, writes Dr. Debra Houry for TIME.
