The Telegraph quantifies the secret to a happy marriage:
4 hugs a day
7 evenings in together each month
2 dinner dates a month
2 romantic walks a month
1 visit to a pub or cinema without children or friends
1 evening away from each other a month
flowers or a gift for the wife once a month
John Bingham writes (excerpt):
The secret of maintaining a happy marriage is four hugs a day, a study has found.
A poll of 4,000 couples found that spending at least 22 periods of “quality time” together every month, such as going for a walk or sharing a romantic meal, were also key to maintaining a healthy relationship.
