Even if smoking wasn't bad for you..... just think of it this way.
Smoke cigarettes? THEN YOU STINK.
There are no exceptions. You reek of cigarettes and it is NOT a pleasant smell and rubs off on whatever you come in contact with. If you smoke inside your home, ALL of your belongings are going to stink to high heaven for years after. I should know b/c my husband and I used to smoke and some of the stuff we still have from then just smells awful and is discolored b/c of it.
I love my brother and his wife, but I hate it when they come to our house or get in my car b/c the smell lingers for days.
Anyway.. when I did smoke, I used to get chest colds ALL the time that used to last for months. I would keep my husband (then boyfriend) up all night long b/c I had uncontrollable coughing fits. And what do ya know.. since I stopped smoking all of those years ago, I haven't had a single chest cold since.
My brother and his wife also smoke, and smoke around their 2 children. Both of their kids are ALWAYS sick and I know it's b/c of the smoking.
