Some broad themes brought me where I am today. At a very young age, my hobby became thinking and finding connections.
At Olduvai, for 20 years, Mary and I had investigated and made a general survey of the overall geology.
I don't think it's any coincidence that I lost my religious faith and 'manned up' in the same year. I was described somewhere as a lapsed Catholic, which is funny because I'm not going back! I want to achieve things rather than live life in an animalistic way.
