Kiss of health, not the kiss of death

According to recent studies, kissing reduces the release of histamines (the chemical produced when you get an allergic reaction). What kissing does is, it relaxes the body and when you're relaxed, histamine production and release is reduced. So the s/s of an allergic reaction, such as runny nose, pruritus [itching], sneezing, bronchoconstriction, etc may be reduced!
So, if you have a history of allergic reactions, pucker up and give your lovey-dovey some WPKOL (aka wet passionate kiss on the lips, if you're not too keen on online jargon). Hehe!
Contraindication: Just make sure the person you're about to kiss doesn't have mono (infectious mononucleosis). Hehe :-P
