Oh, no! I'm young, rich and pretty

Feeling down today? Don't worry, it's not because you're single.

Being at one with the universe does not require a better half - or loads of cash, or good looks or being in the first flush of youth. So say experts who have identified ten points which could hold the key to a happy life.

While money can buy some happiness, top of the list is not being greedy. If you desire less, stop worrying about not being the next Einstein and quit comparing your pimply, plump image to Naomi or Brad, you'll be smiling all the way to the grave.

The findings, from studies around the world collated by New Scientist magazine, show people should stop wanting to match 'unrealistic' media images and understand that photos of celebrities have been airbrushed.

Having good friends, being married and finding God - in whatever form - also help promote happiness. It also helps if it's in your genes, though.

Up to 90 per cent of our happiness can be determined by our genetic make-up, the report claims. Extroverts tend to be a lot happier than introverts.

If all else fails, it does not hurt to do a good deed or just try to grow old gracefully. The elderly are just as happy as the young and rate themselves more satisfied with their lives, researchers discovered.
