It has been assumed since Ancient Greek times that exercise is good for you. Yet until Professor Jerry Morris started to think about it in the late 1940s, there was no real scientific evidence.
Morris conceived the extraordinarily simple idea of studying the health of bus drivers and bus conductors on double-decker buses in London. After all, the drivers spent their day sitting behind the wheel, whereas the conductors were running up and down stairs all day – an average of 750 steps per day.
Lo and behold, he discovered that the drivers had twice as many heart attacks as the conductors.
Morris followed up this study with other grander designs. He discovered for example that postal workers who delivered their mail by foot were significantly healthier than those who drove their routes in vans. But it was the publication of his bus-workers research in the Lancet in 1953 which began the process of transforming attitudes and behaviours worldwide.
He himself was an early jogger, at a time when it was considered eccentric. And well into his 90s he was still swimming, pedalling his exercise bike and walking every day.
He died 28 October 2009 aged 99.
