It turns out it isn't getting rich (or being skinnier) that makes you happy.

It’s sleep and sex that rate as things that make you feel the most content.
Although preferably not together.
A study has found that sex and sleep are the two things that have the strongest association with a person’s wellbeing.
The index, developed by researchers Oxford Economics, found that quadrupling your income causes very little increase to your happiness, while spending time in the bedroom is a lot more significant.
Polling carried out by the National Centre for Social Research, found that the most rested people score 15 points higher on the index than those who struggled with their sleep.
People who are deeply dissatisfied with their sex lives score seven points lower on average than those who say they were very satisfied. Satisfaction improved with sex twice a week, and over eight hours of sleep.
The result was the creation of the Sainsbury’s Living Well Index, which generated a list of the top factors that separated the happiest 20 percent from everyone else. In order of biggest influence, sleep quality, sex life, job security, health of close relatives and chatting to neighbors in other words community) that rounded out the top 5. Daily walks also made the list.
Every study done in the last 20 years talk about how great sex improves your mood and your health. After a few nights of bad sleep everyone knows how big a factor rest is on physical and mental health. However the fact that money doesn’t rank at the top of the list might might be surprising. Researchers found that those who had good sleep and a sex life they were satisfied with had higher “living well” scores than those people with a high income.
