"Although cholesterol is essential to life, we don't need very much of it to keep our bodies running well.
The problem is that many of us eat a diet that is too high in saturated fat and trans fats, and this can stimulate the liver to produce more cholesterol than the body needs.
Some of this excess LDL deposits its cholesterol "baggage" in our artery walls — including those of the heart — resulting in the formation of soft atherosclerotic plaques.
During a discussion with a patient recently, she asked me, "What's the difference between good and bad cholesterol? Isn't it all the same when it's building up in my arteries?"
The answer is that it's not the cholesterol itself that is good or bad, but the particles that carry it. These particles are called lipoproteins (the lipo is short for lipid, which means fat). High-density lipoprotein (HDL) and low-density lipoprotein (LDL) are two of them.
It's the protein part of the lipoprotein particle that acts like a shuttle bus, transporting the cholesterol (and other fats like triglycerides) through your bloodstream to where they are used, stored, or excreted by the body. Lipoproteins are necessary for transporting fats because fat is not soluble in water or in blood."

After some research online yesterday, I found a reasonable 6068 (6' wide, 6'8" high) patio door. It didn't need to be fancy, tinted, or doubled glazed, as the western and southern windows in the guest house are not either, as they are in the shade. The northern ones are double glazed, though, as a lot of wind travels across the fields behind us.
It was at McCoy's Building Supply: http://shop.mccoys.com/building-materials/doors/sliding-aluminum-patio-doors/p.8538, It is the only McCoy's in my area that listed having that door, and it is in Cleveland, TX, but they are closed on Sundays.
So, I couldn't call to make sure they had one in stock until this morning. They did, and it is cheaper because it comes unassembled, which is just what I needed, to fit in my van.
I also called a glass company to see how much it would cost to have them put new rollers on my old door. The receptionist gave me a price only $4 less than the new door. But I don't really think she knew what she was talking about!
Jay wanted to go with me, so I had him help me take the second bench seat out of the van. (We took the back bench seat out when I bought the van.) It just has a button to release the seat belts, then a catch to lift up, and the seat can be removed.
We drove the backs roads to Cleveland, and enjoyed the country scenery. It is always interesting to see what has been built since the last time you traveled a route. The countryside is getting littered with subdivisions. The lovely woods are disappearing, and housing developments are in their place.
We were so glad we took the seat out, as it went in there so easily, and slipped in between the front seats to support it.
I had felt strangely tired when I got up this morning, though I seemed to have slept well, so when I got home, I ate some lunch, and took a nap today.
