“Date a smoker.”
My friend’s younger sister was overweight. She got married at 21 (I think) to a great guy who happened to be overweight and smoke.
She found out about the smoking on the third date. Her father had been nifter when she was little, and the guy asked her how father died. She responded, “He had a heart attack because he was overweight and smoked”. So the guy said, “So I guess you must hate guys who are fat and smoke (like me)?” She said, “Why should I hate people who are fat? I’m fat myself.”
I don’t know how she felt about the smoking part, but my friend realized she was marrying the guy based on the way she responded to the fat part.
However, I don’t think that being overweight means that you have to marry a smoker. To my knowledge, I only once went out with a guy who smoked, and he was totally not for me.
