We all enjoy a really good kiss, but did you know that locking lips with someone makes you live longer, helps prevent tooth decay and burns calories?
Apart from the obvious bacteria swapping and reducing stress levels, it turns out there is plenty more to know about a good snog with your partner, lover, or whoever else you happen to be swapping saliva with.
