In general I have little patience for big people who eat poorly (I couldn't care less if someone exercises or not) because I think it's so easy to be the right weight if you cut stupid calories.
Easy for me to say, I'm 6'1''. When I was 20 I weighed 165 lb, I'm 180 now. I smoke when I want, stuff my face with whatever food I want. My doctors cheer my good health.
However:
I really despise a doctor talking about anything that isn't on my agenda. My health, my money, I lead the convo. For me a doctor is someone, probably not as intelligent as me (or most people on this forum) who has domain knowledge and access to medical services I need.
Cut the crap and give me the service I'm paying for not a bloody lecture.
Dentists can stop with the floss already. I know, I don't care.
