Steve Peters is a British psychiatrist, athlete, and author. He is an advocate of looking after your emotional health, and believes the chimp brain acts on impulse with no regard for consequence, and the human brain makes judgments based on facts and truths. The Chimp Paradox was the most successful selling self-development book of 2014. Peters currently competes in the M60 age group in Masters Athletics, and has held multiple World Masters Champion titles, and World Records over the 100, 200, and 400 metres.
