People are going to be living quite soon for 100 years. Our idea of how a family works no longer applies. It's no good saying you're going to have children for 15 years and then you're going to retire and have hobbies, because you've got 40 more years to go after 60 and you're in good health until 90 or something.
The British have turned their sense of humour into a national virtue. It is odd, because through much of history, humour has been considered cheap, and laughter something for the lower orders. But British aristocrats didn't care a damn about what people thought of them, so they made humour acceptable.
