Is "Smoking" really dangeruos..??

Its like a bomb - never safe and always a chance of getting sick. The list of possible illnesses is long - cancer, heart attack, vascular disease, stroke, hypertension, pschological illness etc etc etc etc etc. Now just because some people did not get any disease does not prove a thing except that maybe they were lucky.

it's really dangerous, take care of your health, your father is a lucky man

Yes, ofcourse smoking is dangerous for health. It can cause any type cancer or other danger diseases. It shortens the life of a person

i think absolut yes it's not a secret even if some smoking men become very aged

Smoking harms everyone in general.Maybe your grandpa has an amazing resilence.But,I'd like to say that he'll be in the minority.

I think it isn't and it is only deflating your conditions and other stuff , so i wouldn't advise when you sport...
