Testosterone, personality and leadership
A few years ago I was on holiday, in Malta, with a group of friends. We were enjoying the last of the summer sun and over a few glasses of wine we reflected on the stage of life we were at; middle age. At the time I was 40 and felt full of energy. I still felt that I had a whole career and life ahead of me. I felt confident and strong. I mused that because life expectancy is 80, based on my age I was at the equivalent of July 4th, if one year was a human life.
