Cathy, it may be a reflection of America's aging population and their increasing political clout.

Youth comes to rich countries today by immigration which America has sort to restrict in contrast to Canada, Australia, New Zealand and pre-Bexit UK which had flows from its colonies and later Eastern Europe. The latter have young prime ministers and cabinets. Our Joe Biden is definitely the old fart on the world stage.

Many thanks

I recall Peterson as a whack-job!
