The Surprising Way Smartphones Protect Your Brain

Smartphones protect your brain from cognitive decline, a study of 412,000 people proved it. In Episode 6 of The Mind & The Machine, we cover the research the headlines ignored, and what it means for you.

Researchers at the University of Texas at Austin found that adults over 50 who regularly used digital technology were up to 58% less likely to show signs of cognitive impairment, a protective effect comparable to regular physical exercise. If nobody told you about this study, that's exactly why this episode exists.
