Small and sprightly is the way to be

After a lifetime's observation of my fellows, I have decided that I am the Wrong Shape

I've often wondered why I have less energy than small, slim people, and I still don't know the answer, but what I do know is that theirs is the best shape to be. I've posted before about our amazing neighbour, who is much older than I am and has ten times my energy. And then there is our friend, Di, who at eighty plus bounces about and wears her poor husband out. And just now, when I was  at the lovely horsey place buying horsey things, there was this small, sprightly assistant, whose colleagues say she rushes about "like a hamster in a wheel". 

I am tall. I am not at all fat, but could never be described as sprightly. I often lack energy. I'll just have to live with it. Sigh....
