I can't believe what i have just read.
Kissing was developed 'to spread germs'
'It isn't the most romantic theory, but scientists believe kissing was developed to spread germs which build up immunity to illness.'
What a way to kill the romance.
Sweetheart, i'm not kissing you because i love you, i'm kissing you so you need to build up immunity to some germs.
The only thing is that people have been kissing for hundreds, if not thousands of years. How did they now back then that they must kiss each other to help provide the woman an immunity for when she is pregnant.
Take a look and see what you think.
