I hear ya on the shopping. It takes me a while in the Produce department, but once I stock up on the fruits and vegetables I am almost done, there are only a few other things I buy in the rest of the store. For example, out of the whooooooole cereal aisle, I only buy one thing - plain oatmeal.
Yes, there are tons of sick overweight people. The sad thing is, most of the people who have a good body size/shape that LOOK healthy... turns out they aren't. People I thought were fine, later you find out that they have some thing that you can't SEE but is a big problem, nonetheless. Chronic sinus infections. Ear infections. Yeast infections. Heart blockage. Blood clots. Various and sundry cancers. Arthritis. ETC.
The big question is... would the TRULY healthy people please stand up?
