I have not read all the responses; but, for me it comes down to this: We nurses (I'm still in school) were professionally trained and given the knowledge on how to live a healthy life. It would be very odd to tell a person they need to lose weight or quit drinking and smoking if we are doing it ourselves. How are we credible? ...and by the way, I know what you're thinking...I'm still in school, what do I know...I'm too young to know about menopause and all the other previous excuses. Well, I'm in my mid 50's and I have been working blue collar jobs all of my life. Now, I'm changing direction and careers. Why would someone go to a fat doctor to learn about Diabetes? Why would someone go to an Oncologist who smokes cigarettes in- between patients? As an older person, I see how the general public judges people, it's natural. Most people judge by appearance only because that may be all they have to go on. For that reason, I am going to try hard to eat healthy and lift weights as much as I can so that I can be mentally / physically / esthetically healthy. After all, it's going to be hard enough to get someone to hire me at an older age anyway, once I get out of school!!
