1. Track This At 34 To Predict Your Heart Health At 63
 |
The cardio you do in your 30s buys time for your arteries in your 60s.
Researchers in Sweden tracked people for nearly 30 years, measuring their fitness at age 34 and checking their arteries at 63. Those who were more aerobically fit at 34 had healthier, more flexible arteries three decades later.
Stiff arteries are one of the best predictors we have for heart attacks and strokes. Here’s the part that surprised me: fitness predicted arterial health better than any cholesterol panel.
Those advanced lipid markers everyone’s chasing? In this group, they didn’t predict stiff arteries at all. VO2 max did.
That said, the study was a small Swedish group, so this doesn’t mean to toss your blood work out the window.
But the signal is clear: the more you put in now with your cardio, it just doesn’t disappear. Your heart is always keeping the score.
2. New Breakthrough In Alzheimer’s Research

Alzheimer’s is one of the most destructive diseases on the planet. More than 7 million Americans are living with Alzheimer’s. Worldwide, dementia affects over 55 million people, with Alzheimer’s being the most common.
Researchers took in an 80-year-old woman with advanced Alzheimer’s who was 10 years into the disease. She had only spoken single syllables for 5 of them, couldn’t control her bladder, and needed help to walk.
She took 5 g of psilocybin mushrooms under medical supervision. About 19 hours later, she started talking for hours, telling detailed stories about her life. Over the next few days, her family watched her dress herself, walk on her own, and regain bladder control.
The catch: the effect was temporary. The researchers titled their paper “Transient” and warned that this is not a reversal of Alzheimer’s.
It was one patient, with no cognitive testing, and a dose high enough to risk a dangerous spike in blood temperature.
Still, it raises a great question: what if this disease isn’t gone, just locked away, waiting for the right key?
