My wife and I were careful in our younger days, using margarine instead of 'that nasty butter'. That was until we went to France and lived there for 8 months.

My wife and I were careful in our younger days, using margarine instead of 'that nasty butter'. That was until we went to France and lived there for 8 months. We saw that the French used lots and lots of butter in their cooking, but were generally not as obese and appeared to live longer and healthier. We changed our views, and started using butter again. That was 10 years ago. (Butter also tastes better, and doesn't cause as many problems with bowels.)
