Matt Cardy/Getty Lottery winners in Sweden are more satisfied with life than those who lost the lottery, says a new study by scientists in Sweden and the US. What's more, that boost in satisfaction doesn't fade over time, according to the study. Previous studies have found that winning the lottery doesn't ultimately change our life satisfaction or happiness. It's probably best to rely on things other than money — like close relationships — for health and happiness. Social scientists spend a lot of time thinking about all the ways your life might be different if you came into a massive fortune.
