She is obviously a good gardener and if she is in grubby work clothes and dirty hands, well that goes with the territory.
I loathed her years ago, called her the Braless Wonder. I will never forget the look of horror on Nelson Mandela when she transformed his garden in his traditional homeland into something that should have been in Ideal Home Exhibition. Poor man.
There is a difference between youthful size and putting on enormous amounts of weight in 50s and 60s which she obviously has. There is a need to keep weight under control for health issues. We nearly all struggle with that, and I am well overweight but I couldn't let myself get to that size.
