 I walk as much as I can both up North and in Auckland, climb steep hills, kayak, play tennis and sometimes play golf but today, after a day of playing in a lawn bowls tournament I'm bloody stuffed.

There were about 60 people there playing bowls from 8.30 AM to about 4 PM and I was almost the youngest person there. I'm 65. Some of them were in their late 70s and I swear one woman looked like she was a nonagenarian. They all seemed to handle it OK and looked quite spry as I was fading in the afternoon.

I've noticed this before, when playing 18 holes of golf. I'd be happy to stop after 9 holes but these old buggers just keep going on and on like the Energizer bunny.

It's all a matter of doing what you're used to I guess. I'd be exhausted after cleaning slippery showers after an hour like Robert does but then, he'd probably be totally shagged out by having to have a sleep in, a late breakfast, reading the Listener and doing the crossword followed by dip in the bay.  Go figure.
