Brain Rules for Thinking Smarter

This document summarizes a webinar presentation by Dr. John Medina on his book "Brain Rules". The webinar focused on three key principles from the book: 1) Exercise boosts brain power and aerobic exercise improves cognition, 2) Multitasking reduces attention and increases errors, like the impairment from drunk driving, 3) Stress damages cognition and learning as the brain can actually shrink from long-term stress. The webinar discussed evidence from research on how physical exercise, multitasking, and stress impact the brain and cognition.
