Dr. Cam McDonald is back and this episode is seriously fascinating. And valuable. There is so much great information in this chat, you’ll want to listen twice. Along the way, we talk about how, just being around certain people can be good or bad for your health. Why your job might not be a good ‘fit' for your biology. Why certain colours, clothes, music and environments can boost or suppress your immune system and impact your nervous, cardiovascular, respiratory and endocrine systems, for better or worse. And lots more.
