Recently i went to the hospital to check see the doctor and i was told the doctor to attend to me will be back soon, while waiting, he came in and from the look of things he had gone to smoke, it got me thinking, can it be that they are telling us not to do this and that and if you follow them you wont eat anything because everything is bad to health, no drinking of alcohol, smoking of any kind and the list is endless, why would a doctor now turned around and go smoking?
Of course they do... They are humans and in their job they have to lie sometimes in order to alleviate the "bad" news.
They now what it is bad or good for our health but that doesn't mean that they follow it in their personal lives. Consider other professions as well. Lawyers for example make small illegal actions in their everyday life many times. That doesn't mean that they don't know it, they do it in their consciousness.
