Doctors have discovered, just this week, that a neighbour has survived for 86 years with just one kidney.
Even more disconcertingly, they are saying that this lack of a second kidney was probably due to his having been born to a mother who was in the change. It’s the sort of thing that can happen at that time, they say.
I haven’t been able to find any mention of this ‘fact’ on the modern web, but we are talking here of a woman who must have been born c1880, old enough to be my great grandmother; things were no doubt very different then.
And her son has had the great benefit of having been born a member of the Golden Cohort, to experience unprecedented improvements in health & longevity.
