The secret to a happy marriage is kissing and saying 'I love you' 10 times a week and going on three dates a month, an American report has revealed.
The detailed study of 1,000 married Americans also found three surprise romantic gestures and 10 deep and meaningful conversations each month are key to a harmonious relationship.
Having three shared hobbies and interests and going on two vacations a year are also among the requirements for romantic bliss.
