Couples share the maximum number of kisses – 31 a week – between their first and second anniversaries, a new study has found. According to the Heathrow airport study, lovers typically kiss 21 times a week, the Daily express reported. However, the actual number varies as the relationship evolves. In the first six months, couples kiss 25 times a week, reaching 31 in their second year and falling to 19 after five years.
The study also found that one in 20 British adults never kisses his or her other half, but there are 200,000 reunion kisses a year at Terminal 3, where the film Love Actually was shot.
