In a hurry to register? "Wisely and slow; they stumble that run fast."
And, by the way, "TEAT" rather than "BREAST" would have given you room for the apostrophe.
PS. This medical evidence you speak of....where is it? Cite at least one study. There was "evidence" that smoking caused ulcers, until they discovered helicobacter pylori. There was "evidence" that smoking caused cervical cancer, until they discovered HPV.
As Max said, above, there is irrefutable evidence that 8 of the 10 oldest lived humans were smokers.
On the other hand Jim Fixx, widely regarded as the father of the modern jogging craze, dropped dead at 52.
There is medical evidence that smokers live far shorter lives on average than nonsmokers.
Tell that to the Japanese - male smokers' life expectancy: 76.5 years (2nd highest in the World); % of Japanese males who smoke: 59%. (By the way, this is not "medical" evidence, but "statistical" evidence.)
What is my point? Your supercilious certainty that I will die young and you will live to a ripe old age because you do not smoke is unproven, unfounded and untrue.
