A 15-year study of over 4,000 adults found that those eating the most riboflavin (vitamin B2) had a 49% lower risk of serious dementia, compared to those eating the least. It's an observational study, not a guarantee — but it's a strong pattern worth paying attention to.

Rally tries a simple move on his living room floor this weekend — sit down cross-legged, stand back up, without using hands or anything else for support. It did not go well, at all. Did you know there's a real science-backed test built around this, and it might be one we should try to master. Think you can do it?

Rally's been a daily shower guy his whole life. But it turns out that habit might be doing his skin more harm than good. Today he digs into why dermatologists say we older adults can (and probably should) shower less often, plus the simple tweaks to your routine that can really save your skin — and your time!

Rally always figured tired, heavy legs were just part of getting older. Turns out there's a "second heart" working overtime down there — his calf muscles. This episode breaks down why those muscles matter more than you think (Mayo Clinic study), the warning signs Rally wishes he'd caught sooner, and the super-simple things you can do right away to get a leg up on keeping that second heart of yours pumping strong.

National Geographic magazine asked 1,000 American adults a tough question: What would you give up for an extra decade of living in good health?
