Oh dear. I do hope it was nothing personal...
Surveys have decided that the beginning of old age is anything from about sixty five and eighty years of age.
My Neanderthal band in SONG HUNTER has an old lady amongst them. She’s called Pearl, and she’s the grandmother of my heroine Mica. Pearl is nearly blind and her joints are stiff. She’s too old to hunt, though she’s full of life and nobody’s fool.
How old is Pearl?
Well, Neanderthals seem to have grown up a little faster than Homo sapiens in Western Europe does nowadays. Neanderthals were more or less full grown by the time they were fifteen.
That meant that I could have a guess at the age of my old old lady.
After doing all the arithmetic, it turned out that the ancient Pearl was forty three years old.
