According to the United States Constitution the president must be at least 45 years old because “Wisdom cometh with age.”
So forty five was considered old back then.
I remember when it would make the news if someone lived to be 100 years old, but that’s not even unusual today.
My husband used to work at a nursing and retirement home. When he started working there most of the residents were in their 80s and a few were in their 90s. When he retired 20 years later most were in their 80s and some in their hundreds.
And, when I was a kid, puberty was expected to begin in the early teens. Now it’s not unusual for girls to reach puberty when they’re only nine years old.
So, if lots of people start to reproduce before reaching their teens, and lots live more than a hundred years, our planet will sure be crowded.
And, if people predicting that the oceans will rise are correct, there will be less land so humans - and animals - will be so crowded we can hardly move.
Will we be wise enough to deal with that?
