Hey! don't bealive that hookah is very harmfull. I mean 4 days ago, on the news in my country they said that 1 puff of hookah is equal to 70 puffs of ciggarets. I mean like wtf? That cannot be possibly the truth... i smoke hookah for 2 years, train sports, do jogging and stuff, and i do not smoke siggarets. One a week i drink. I mean anything is bad for you. (even air) if taking it all that way. Well enjoy your shisha!
