Why that lovely, harmless looking kiss could spell death

• Kissing is now a norm rather than an exception in today’s society. We are in the days of Masaku Sevens and related activities - young people are not afraid to publicly display affection.
• I wouldn’t like to pry into other people’s bedrooms, but I believe there must be a lot of kissing going on behind closed doors.

This, on face value, would mean there is love in the air. But no, it’s not just love. Millions of bacteria too are involved in the mix. “When lovers kiss, they exchange a lot of bacteria through their saliva,” says Dr Lubano Kizito. “The human mouth contains a lot of bacteria. Depending on one’s state of health, the oral cavity may contain germs as well as good bacteria.”
