Finding cash and baby giggles are among the top 20 things which make us smile, according to a new survey.

The research, carried out by Co-operative internet bank smile, reveals the top twenty things most likely to bring a grin to our face.

Among the things making the list are bank holidays, hearing a song from your past and seeing an old friend.

However, the old adage that money can’t buy happiness appears to be untrue, as the research showed that finding a ten pound note in an old pair of jeans is the moment most likely to make us smile.

The findings also proved that reminiscing brings back happy memories, with almost half of respondents revealing that looking back at old photographs (47%), hearing songs that remind them of the past (45%) and even fitting into a pair of jeans that used to be too small (41%) makes them smile.

As Britain’s obsession with weather never seems to dwindle, it is clear that good weather also raises a smile, with sitting in the sun (46%), booking a holiday (39%), landing at the holiday airport (33%) and swimming in the sea (28%) also popular choices.

John Barker, head of smile, said: "At smile we understand that money doesn’t buy happiness, but, during the current financial climate we also understand that having financial security and not having to worry about your finances and in particular who you have chosen to bank with is the ultimate ‘smile’ maker."
