Can Meditation Make You Better at Paying Attention?

Can Meditation Make You Better at Paying Attention?

by Dr. Teralyn Sell, PhD | Nov 14, 2026 | Brain Health, Capacity Report, Human Performance, Question of the Week, Sleep

Most of us have heard some version of this promise: meditate for a few minutes a day, and you’ll become more focused. It’s appealing because attention feels scarce. We lose the thread in a meeting. We reread the same paragraph. We open our laptop to do one thing and,...
Is Retirement a Brain Health Plan?

Is Retirement a Brain Health Plan?

by Dr. Teralyn Sell, PhD | Nov 14, 2026 | Brain Health, Health & Wellness, Question of the Week

Retirement is supposed to be the reward. You worked, you saved, you finally get your time back. And for plenty of people, it is a relief. No alarm. No commute. No meetings that should have been emails. But I’ve wondered about the part we tend to skip over: if work has...

Can Loneliness Change How You Think?

Can Loneliness Change How You Think?

by Dr. Teralyn Sell, PhD | Sep 28, 2026 | Brain Health, Question of the Week, Social Connection

We tend to talk about loneliness as if it belongs in the same category as a bad mood. You feel lonely. You call a friend. You join something. Problem solved. But I wondered whether that framing misses something bigger. If loneliness persists, does it merely make life...
