I found all natural, hormone free beef liver for 99 cents a pound! That meant I got meat for two meals for just 58 cents. What a bargain!

If you have eaten much beef liver, you know the worst part is biting into one of those tough parts that just won't chew up. There is nothing like sitting in a restaurant chewing and chewing on the same bite of liver and wondering whether to take a deep breath and swallow the thing whole like a piece of gum or spit it out in your napkin.

The tough parts are the membranes surrounding the tubes that run through the liver. Some of them are large, some are small, but all are tough. I tried cutting them out with a knife. Impossible! Raw liver is too slippery. I gave up and switched to cooking chicken liver. It's much easier.

After I started the BTD, and realized how beneficial beef liver is to a Type O, I decided to give it another try. In the meantime my mother-in-law had given me a pair of kitchen scissors for Christmas. My mom never used scissors in the kitchen for anything except opening stubborn plastic packages, so this was new to me. I soon learned to use them for skinning poultry, trimming fat off meet, slicing pizza, and cutting dough. I used my Christmas scissors so much that they were often dirty when I wanted them, so I bought a second pair.

When I tried beef liver again, I went after the tubes with my scissors. The slippery raw liver was no match for kitchen scissors! While I was at it I cut the liver into pieces about 1 inch by 1 inch. That made it easy to cook in a skillet coated with cooking spray. The dog, who swallows everything whole anyway, thought the discarded tubes were wonderful.

Today I began by grilling an onion in a little butter in my skillet. When it was about half done I added the liver. I covered the skillet, reduced the heat, and went to get ready for school. When I got back it was all tender, tasty, and very beneficial.

The composer John Cage (who actually composed the world's first piece of music that was entirely silent, titled ‘4:33') was once offered the chance to sit in a completely sound-proofed chamber at one of the large universities.

Cage, who had excellent hearing, entered and almost immediately commented that he heard a low whooshing sound. He was informed that this was the sound of his cardiovascular system. A few minutes later he began to hear a high pitched siren-like sound, and was told that this was the sound of the neurons of his nervous system firing.

After a long period of concentration, he managed to tune out these two sounds and began to hear a chirping sound, like thousands of migrating birds.

This, he was told, was the sound of the Brownian Motion of the atoms forming the oxygen, nitrogen and carbon dioxide molecules in the air of the chamber.

There are many examples of similar types of low-threshold sensitivities. Most people can smell or taste as little as one molecule of an aromatic or flavorful substance. As Cage demonstrated, our powers of deep listening are similarly discreet. Perhaps even more impressive than low-threshold listening is our ability to zone in on certain bandwidths of the auditory spectrum. As any new mother can tell you, they know when they hear the crying sound of a baby whether that baby is their baby. Next time you are in a busy shopping mall or train station, ask a spouse or child to move at least 150 feet away and engage in a conversation at normal volume. Despite all the ambient noise and voices, you should be able to clearly hear their voices above all others.

It is amazing what we can sense when we stop trying to sense it.
