Hardly, she’s had to smile at a procession of increasingly less capable prime ministers for decades. She was well used to this.

Not getting a real day off for 73 years probably had more to do with it. Or, you know, just being 96.

I hate to say it but that is one of the dumbest things I've ever read.

Absolute hogwash. If it was a strain it was because swearing in ministers is real work, a lot of it, and she is 96 years old.
