Being complemented for losing weight, getting a bargain and finding a lost tenner in your pocket are among life's top 50 'sweetest moments', according to new research. A study of 2,000 UK adults revealed the little things which make them happy - such as getting asked for ID even though you’re clearly old enough to drink. Climbing into a bed with fresh sheets and the aroma of bacon cooking also help to brighten our day. Other happy moments include seeing a dog with their head sticking out of the car window, being surprised with flowers or chocolates and the first coffee of the day. The research was commissioned by www.spirini.com, a mobile phone app for deal hunters, which launches this week.
