All valid points.
Moderation is the key my friend!
My wife busts my balls every time I have a beer, since she don't drink alcohol she has a problem with me drinking , but I overlook that because she lets me do most of the cooking, and I cook some off the wall stuff.
Are you sure she's just not set in her ways and is just looking for an excuse to have it her way or no way?
I smoked many years myself, started at 12 yrs old, gave it up when I met my wife.
What I did to my body from the time I was 12 til I met my wife I should be dead!
There are far worse everyday things that we are doing to our bodies everyday, being overweight, lack of exercise, taking pain medicine, sitting in traffic, living in congested areas or factories, poor diet, stress, fast foods, carpet cleaners and sprays that are inhaled, the chlorine absorbed by our bodies every day from our water...the list goes on and on, just wanted to point out a few everyday things that harm us.
However, If you plan on cooking all the meals on the grill or smoker, I would have to agree with your wife.
