The smoking comment reminded me of an incident about 45 years ago when a customer came into our health food shop for advice on giving up smoking. My opening comment was always that only the smoker could be determined and as soon as they said, "I'd like to give smoking but..." they were beaten.
I then said that if ever she wanted to have a baby she should stop as it stunted the unborn baby's growth. "Oh," she replied, "I smoked all through pregnancy and it didn't affect the baby." I asked how the baby was. "Oh, it was stillborn."
