Hello and welcome to the Intelligence from the Economist.

In New York, I'm John Fassman.

And in London, I'm Jason Palmer.

Every weekday, we provide a fresh perspective on the events shaping your world.

As humans live longer and healthier lives, there's been a boom in the number of grandparents

in the world.

And with people opting to have fewer children, there's more grandparents to go around

for each.

And an increasing amount of America's political turmoil in recent years has involved its far

right groups.

They once had a sharp focus only on racial hatred, but some new data reveal a different

fixation to whip up unrest, LGBT people.

Last week, a surprise announcement in New Zealand marked the end of a story political career.

For summer, I had hoped to find a way to prepare not just for another year, but another

two, because that is what this year requires.

I have not been able to do that.

And at here, full goodby, Jacinda Ardern stepped down as the country's leader.

And so today, I'm announcing that I will not be seeking real action.

And then my term as Prime Minister will conclude no later than the seventh of February.

Few saw that a part you're coming.
