"Pretty Cool for a Pensioner"??

First I want to say: I really adore Joanna Lumley!
I LOVED her as Patsy in "Absolutely Fabulous" - so hilarious, so blunt - so wonderful!
Then I loved her campaign for the Gurkhas.
And I think she is a very pretty role models for the "Young at Heart".
But I didn't like her last advert for "In the home with Sky Go":  www.youtube.com/watch?v=WLCGphxg6ds
There she is shown as a lovely to look at person - but behaving like a woman of the Fifties.
I don't believe that she (!) all these years had endured to watch (for her: boring) motor races with her husband without going to buy her own television set... And a bigger one as that little laptop she uses in the kitchen!!! I firmly believe that Joanna has what Virginia Woolf called "A Room of One's Own." (And she was not speaking of the kitchen).
But what really annoys me is that seemingly everbody does believe that people, as soon as they become pensioners - and in lovely England they can become that with 60 years, I have heard - get weak in the brain, lose their marbles, suddenly don't know how to use a mobile or computer.
Hey - we are speaking of people who became pensioners - so they must have been working somewhere - and where do you not need a computer nowadays? So: people who where managers, actors, mothers, whatsoever - suddenly are depicted as Rip van Winkle? König Rotbart? Having overslept the technical inventions of the last decades???
"Pretty silly", I say.
You are a great person, Joanna, you are a role model - don't play "Little silly me, not wanting to annoy big mighty husband". You are worth far more than that.
And: Old is not a synonym for stupid.
