London: If you think the passion to kiss your partner is missing in your life, it could be due to your marriage.
A survey in Britian has found one in five married couples does not kiss for a whole week and when they do, it is usually a quick smooch lasting not more than five seconds.
But younger sweethearts are more romantic, the survey finds, with those between 18 and 24 saying they lock lips with a partner 11 times a week, the Daily Express reports.
The findings were released in a campaign by the British Heart Foundation to teach reviving skills like the kiss of life to schoolchildren as part of the national curriculum.
Celebs also revealed their most memorable kiss for the charity's YouTube video.
British Olympics gymnast Louis Smith revealed his was at school, kissing "that one girl that's older, who you think is amazing."
"My friends jumped on me, celebrating like I had just kissed Victoria Beckham."
ITV weather girl Clare Nasir said: "My greatest kiss was for my daughter at birth. She was six weeks premature and we almost lost her. It took us six years to have a baby and it was the best day of my life."
