Can being a CNA be compared with Smoking? My boyfriend thinks so..?

absolutely not your boyfriend is trying to make a very weak argument to justify his smoking, tell there is honor in what you do because you help take care of people who are unable to do it by themselves, where as he is doing something completely un healthy make this argument to him in that case. since you don't check vitals on the elderly or assits someone going to the bathroom when you are with your boyfriend he shouldn't smoke when he is with you.
