I am one of the worst golfers in the world, but have always enjoyed the game. My PCP told me that for golf to count as exercise, I would have to use a pull cart. So I did, but found over several years that it was harder to walk the long, uphill fairways. I attributed it to being in poor condition, so I joined a gym. I did pretty well at first but soon found that after each exercise I walked to the water cooler, supposedly for a drink, but actually to catch my breath. In December 2008, I realized that I was probably sick.
