I was thinking he should take up gaming. Golf, unless it is on a computer, would be more tiring than bowling.
How is golf more tiring than bowling? Unless you have to walk between the holes. Even then it's not that tiring.
Walking isn't much exercise unless you walk very far.
And the distance between holes isn't that far, unless the park or whatever is massive
Got a golf park near here, the distance between the holes is short.
