How many times does the average person laugh a year?

The average adult manages just seven smiles a day - and at least one is probably false, according to a study.

It found even the most cheerful of us smile only 11 times a day, while the grumpiest produce just one.

The poll of 2,000 adults found the 51 per cent of us who admit to a daily false smile reserve it for our bosses.

Despite our relative unwillingness to smile, we love receiving them. The study found nearly a quarter of us revel in a smile from a lover, and around a fifth in one from our children or another family member.
