How many time a day or week do you kiss your sweetheart? If you actually had to count how many times you kiss your significant other, could you? Well, no need to get out a calculator because a new survey by the British Heart Foundation finds 20 percent of married couples kiss once a week.

OK, so when you do kiss your husband or wife, how long do you kiss for? The survey finds couples who are married kiss for 5 seconds, on average. And, 18 percent of couples don't kiss for a whole week.

Now, does kissing decrease as you get older? The British Heart Foundation found 5 percent of the people polled over the age of 45 get more than 30 kisses a week, and, those between 18 and 24 kiss 11 times per week.
