Tapping into our brain's happiness chemistry

A healthy brain both offers and thrives upon the happiness hormones dopamine, oxytocin, seratonin, and endorphines. By making a few simple changes to our routines, environments, and lifestyle, we can use chemistry and biology to multiply happiness.(Keeping in mind, of course, that there's a lot more to life than happiness.)Join Greg on this walking-optional meditation. And bring a pen to jot down your ideas that come to mind.
