1: Why do you think the idea that we only use a small part of our brain is so popular in movies and books? What would happen if we actually used 100% at once?
2: Many people claim to be "great multitaskers." Is this a sign of an efficient brain, or are we just distracting ourselves?
3: Does having a smartphone make our brains "lazier" because we don't have to memorize phone numbers or directions anymore?
4: Think about your most productive day ever. What were the internal and external factors (sleep, food, environment) that allowed your brain to work at its best?
5: Do you think apps and games designed to "exercise the brain" actually work, or is it better to learn a completely new skill like a language or an instrument?
