I an not concerned (as defined by anxious or worried). I just believe as a good steward of our resources.surely you must be concerned about your health, otherwise you would not visit the doctor or take any medications that you may need. If, like myself, you have high blood pressure, where the numbers can be a problem, this is a concern, and needs to be treated by medication. You says, "I am not concerned or worried about getting pneumonia", then why get any medication to stop this? pneumonia can kill you if left untreated, so to get it will concern any normal person. I think that you are trying to sound "tough".
I'm not trying to sound tough. I just don't think that much about health until I get sick or injured. Maybe I should, but I don't.
I really do not worry about my health. I just go in every 6 months, get labs done, prescriptions refilled, etc.
If my physician recommends a vaccine I just go off that recommendation. That's what they are paid for.
