Of course you were made aware of the dangers. Surgeons General for the last 30 years have been preaching about diet and health issues. Television has specials about health problems in the country. You can't go a week without reading something in the newspaper. If you are unaware of the dangers, you have been living in a reclusive monastary and are in no danger from McCrap.
I learned basics of diet and such in grade school and maybe high school. This stuff is not a secret. It shouldn't have interfered with your absorbtion of Visual Basic...
McDonalds did not lie about anything as far as I know. They sell cheap (more or less) fast (more or less) food (more or less). The use salt and fat to make it taste good. The food is certainly not addictive. Lazyness may be. You can eat the stuff and live. If you can't tolerate the gup, *DON'T* *EAT* *IT*. As I pointed out earlier, you can eat cheaper (I seem to recall that this is a concern for you), and healther if you want to.
The dangers are from excess, not the grease burger. That is an individual sort of thing. If you order a McGlutton burger and supersize it, that's a reflection on you, not the chain. Again, they are not doing anything wrong except cosseting your own vices. You could of course, take the point of view that they shouldn't do that, like a bartender cutting you off when you've had a few too many. Or you could take responsibility and quit whining.
