What sort of idiot am I?

To go to a new exercise class on the hottest day of the year so far and, instead of taking it easy and finding my feet, throw myself into it at full pelt.*

My arms were already aching a bit after digging at the weekend and using my wrist weights on Monday; today every bit of me aches. 

And in between we had some grandchildren and a puppy for a no-sleep-over as their parents were going to an Arctic Monkeys concert.

I'm hoping a dip in the sea later will ease my aches. Having a pool has made us lazy. We very rarely go to the beach as it's "too busy, too difficult to park, too crowded". But really with all this glorious weather we have to.

* Which was still slower than the one-legged man.
