India, Oct. 5 -- Happily ever after begins after marriage, or so we are often told. But from a scientific perspective, does marriage really make people happy? A recent long-term study examined the correlation between happiness and marriage, suggesting happiness comes much earlier. Moving in with a partner adds some satisfaction, but the main boost comes when a relationship forms. Marriage adds very little 'extra' happiness. Perhaps a few decades ago, the increase in happiness was more significant, but today, it remains largely unchanged; this level persists from the moment the relationship is established. The key takeaways possibly hint at life satisfaction coming more from being in love. Marriage is not the magic switch for happiness, especially in countries where live-in relationships before marriage are quite common. So, the next time your parents or relatives nag you about the doom awaiting you if you're not married by 30, point them to this study; it's a reality check: marriage, it turns out, doesn't offer anything extra beyond cohabitation or a committed partnership....
