This happened to be in the news today
http://www.bbc.co.uk/news/health-12193602I would like to draw your attention to this bit.
The results reported here should serve as a stark warning to those who are considering starting to smoke cigarettes.
Who the hell weighs up the pros and cons of beginning to smoke?
Pros.I'll look really cool
I can practice smoke rings
It will be a great excuse to get away from boring people at parties, by nipping out for a cigarette
Hot girls might ask me for a light, and I can engage them in conversation
ConsIts expensive
It smells
It might kill me
Ok 4-3 in favour of smoking. I'll pop down the shops.
Scientists should be encouraged out into society more.
