Summary

It took 3,000 years for our brains to develop to this point — and about 30 for it to get scrambled by screentime. Richard E. Cytowic, professor of neurology at George Washington University, joins host Krys Boyd to discuss how our attention is now pulled in multiple directions, how that affects our neurotransmitters and dopamine levels, and to offers tips on how to get our habits back on track for a healthier mind. His book is “Your Stone Age Brain in the Screen Age.”

1:04.3	was an old-school call-making flip phone.
1:07.4	But for all their convenience, our newer tech devices, with blazing fast processing speed are the ones that require more energy.
