He wants more corvids...
Very few of us in the developed world such as England have grasped the fact that we are in uncharted territory in term of an ageing population - most people are older than forty; most of the native Brits are even older.
(The many millions of recently arrived immigrants, are Much younger, on average.)
But there are now Lots of very old people:
More than 8% of the population of England are 75 or older - that is comfortably beyond the 'Biblical' lifespan of 'three score years and ten'. And that's about 4.5 million people (from about 55 million total population)
About 5% (one in twenty) are 80 or older.
About 1% (half a million people) are 90 or older!
Such numbers of the ancient and fragile are worth bearing in mind when discussing fatality rates from diseases; since most of these very old people are much more likely to die from an infection than children, or people of working age... or even recent retirees.
And, since average fertility rates are below replacement levels and falling, these numbers and proportions are increasing all the time.
