(to the previous post).
Why did I write that the British are different from other Europeans?
Many studies, the results of one of which are shown in the chart, show that even in marriage, Britons feel slightly unhappier than if they were living alone.
While we see in the chart that in Germany and Switzerland, marriage makes people much happier. Like most countries of the world - USA, Russia, China, etc.
In general, joint family life greatly increases the level of happiness, and conversely, living alone greatly reduces it.
But even in this study it is clear that a distinction must be made between family life and life with children. Having children in these three countries improves happiness levels.
But the level of happiness greatly increases the level of happiness - except for living with a partner (but not including the UK) - good health. We also see again differences between countries. In Germany, a good job greatly increases the level of happiness, but in Britain and Switzerland (especially) not so much. (But an increase in the number of friends everywhere has a weak response to the level of happiness).
