Of course there are primarily unconscious areas of the brain, such as the amygdala, seat of emotion, and the cerebral cortex, seat of consciousness, and clearly they they communicate with each other. When you are in love, for instance, both areas are active, one conscious, one unconscious.
The reality of the unconscious (better term than subconscious, but often used interchangeably) can be demonstrated in several ways. Here are 2:
1. When you are sleeping, you are unconscious. Therefore any brain activity, such as dreaming, is unconscious. You can never recreate exactly this unconscious activity, but may recall parts of it. The parts you recall demonstrate the connection between the unconscious and the conscious.
This is why Freud called dreams the royal road to the unconscious.
2. Try to remember the very first time you saw your wife, or husband, or girlfriend, or boyfriend, or someone very significant you met as an adult. This memory is conscious. Now try to remember the very first time you saw your mother (assuming you were an infant). Where is that memory? Have you forgotten it? Now remember the first 700 times you saw your mother, every single day for the first 2 years of your life. Where are these memories? Completely forgotten? No, they are there, but unconscious. They are all in there somewhere, influencing you even as you read this. Hopefully, she treated you well and you're emotionally healthy. But if she mistreated you, you'll bear the scars forever, manifested by bad behavior, bad mood, and (probably) bad dreams. You'll go to the shrink with your problems, and you'll both be befuddled by the root of it all. And Mom, bless her heart, will never admit that she messed you up.
What you are saying is not that you didn't have enough oxygen in your blood, but that you didn't have enough oxygen perfusing your brain cells to allow dreams to happen. This may have been a doctor's opinion, but I don't think there's any good evidence for it, since there's an enormous difference between dreaming and dream recall. In other words, the low oxygen in the neurons of your central nervous system may have been interfering with the link between your unconscious and your conscious mind.
(I frequently dream that I'm hanging out with a friend of mine who died -- and not in the way that I dream she never died, but in that she is merely not dead anymore.)
This is very interesting, and well said. My grandparents, parents, and only brother are all dead, and when I dream of them, and I still do, though less and less, it is with that same odd sensation. I could never put my finger on it, but that's what it is, that death is a temporary state.
This fits in well with Freud's theory that dreams contain a disguised wish of some sort, in this case the wish that death is completely reversible.
But it could work if batteries were standardized, and vehicles designed so that they could be replaced quickly. Then you could have "gas stations" with a supply of batteries. On a long trip, you'd stop in the station, pop out your discharged batteries, and pop in fresh ones. In addition, the batteries at the stations would work on economies of scale.
HDL and LDL are not "types" of cholesterol but rather are combinations of lipid (fat) and protein. Fats are mostly present in the body in the form of these complexes. HDL consists of relatively more protein and less cholesterol and triglyceride; LDL contains relatively more cholesterol and triglyceride than protein.
It's also important to know your genetic predisposition. For example, if you have type I (very fair skin), getting skin cancer eventually at some point in your life is inevitable: all you need is to live long enough and get enough sun. The type of skin cancer you will get from such chronic UVB exposure is most likely a basal cell carcinoma (not fatal) and 30% of these occur on the nose. As another example, if you have the dysplastic nevus syndrome (DN), you'll will have a higher incidence of malignant melanoma. This type of cancer is related more to acute sunburn than chronic exposure and is much more deadly: if you detect them early they are 100% curable, too late and they are 0% curable. Have a nice summer!
There are many studies showing that doctors who continually remind patients to avoid negative health activity, like smoking, eating bacon and eggs, tailgaiting, or risky sex, have healthier patients than those who don't. As Samuel Johnosn said: "It is insufficiently considered that men more often require to be reminded than informed." So it seems that anyone in a perceived position of authority sending repetitive emails can obtain similar results, at a fraction of the cost of doctors' visits. Just don't expect an overall reduction in health care expenditures, since healthier patients live longer, and people who live longer cost the health system more.
