You can of course go to the above link of The Guardian and read the whole article but here is just a little bit of what NINA CAPLAN says on the subject of marriage:
” . . . . Matrimony may make you wealthier, but the power isn’t vested in any institution to make you happier, or more secure in the psychological rather than the custodial sense. Only the right partnership can do that.
And – surprise, surprise – here is a study that tells us that this is exactly what the right partnership does. Data taken from more than 350,000 people in two UK surveys, analysed by researchers from the Vancouver School of Economics, informs us that married people are happier than single ones, that those in committed relationships, even without the paperwork, are as happy as those who have put a ring on it – and that the middle-aged are the most happily hitched of all. . .
