Gotta run?

摘要

Ihated physical education at school. Cross-country was the worst: cold, boring and lung-burning. "Run, don't walk!" the teacher would shout as we jogged reluctantly through the mud, only to walk as soon as we were out of sight. Over the following four decades, my PE teacher's angry barks have been echoed in the constant media reports telling me that I should run, whether informing me that jogging could increase my lifespan by years or that training for a marathon would make my heart younger.
