Well I lost my mum at 101, and can say that the Queen is nowhere near dying yet as far as I can make out.
She won’t have decades yet of course?, but she will totter on for a bit more.
She is so like my mother in her aging, although I think she is ahead of mum at 95/6 in her aging, so may not make 101.
But on the other hand she will have the very best of care.
I think the fact that we have so little experience of dealing with dying, that we mistake aging as being near death when in fact it is simply just aging. I found that my day to day care of mum until her death has taught me a huge amount about dying, bit late really seeing as I’m 76??.
