Brian Goodyear is a retired recreational triathlete who lives in Honolulu, Hawaii. He has entered and finished four Ironman triathlons, most recently Challenge Roth in 2016. In his work as a clinical psychologist, now semi-retired, he has always emphasized the value of physical exercise as a way of helping to maintain a healthy body and mind. His other interests include reading about the latest developments in physics, cosmology, and evolution, which eventually led to the writing of his latest book, From Big Bang to Homo Sapiens. He also enjoys following football (soccer) in his native England, and listening to music, particularly blues and classic rock.
