Concerning HM looking frail and things...
She *is* looking older lately, but still looking good for her age. (Of course she's having the best treatment when it comes down to medical things or things in general. Plus the genes from her mother...)
She *is* in fact walking more bent over, but as has been said, she still walks very well. The *only* thing I am always a bit worried of are her shoes and her heels. Apparently she feels comfortable in them, but given her age...
Shortcut: IMO she's ways from being frail ALTHOUGH she's lately ageing ( a bit )
If she remains like this (without falling etc) I bet she will be able to beat her mothers age.
I think the Queen looked surprisingly well today at the Queen's Speech, much better actually than last year when she had to wear the crown and all the state regalia. Prince Charles, on the other hand, looked old and frail to me (although other posters in the State Opening of Parliament disagreed).
