The brain is a tissue. It is a complicated, intricately woven tissue, like nothing else we know of in the universe, but it is composed of cells, as any tissue is. They are, to be sure, highly specialized cells, but they function according to the laws that govern any other cells. Their electrical and chemical signals can be detected, recorded and interpreted and their chemicals can be identified; the connections that constitute the brain's woven feltwork can be mapped. In short, the brain can be studied, just as the kidney can.

We're in essence allowing our spirit to come to terms with all the conflicts that we build within ourselves. Disease is after all a conflict within the tissue itself. Memory fading within the tissue, conflict of our actions or thoughts, our lives are not seamlessly running together in some way for ourselves, and had not been for a long time before we get to the critical point of a disease.
I didn't notice I was crying until a stewardess came by and gave me a tissue to blow my nose in. Her arm and wrist were slender and they formed a pretty arch, like the limb of a fruit tree, as she poked the tissue into my clenched fist. She didn't look at my eyes. It was a perfect gesture, an expression of indifference and concern, which is the most a drunk can ask for.
I look at ordinary people in their suits, them with no scars, and I'm different. I don't fit with them. I'm where everybody's got scar tissue on their eyes and got noses like saddles. I go to conventions of old fighters like me and I see the scar tissue and all them flat noses and it's beautiful. ... They talk like me, like they got rocks in their throats. Beautiful!
Now the leatherback turtle overcame the heat issue via a simple, but evolutionarily impossible solution; it is the only reptile that possesses fatty insulation known as brown adipose tissue, and the only reptile that regulates a high body temperature. This brown adipose tissue is the expression of the UCP1 gene, and, aside from the leatherbacks, is found only in mammals, amphibians, and fishes. Not one other reptile has UCP1.
Here's how it works. Your immune system protects you from all kinds of nasty bugs and helps repair tissue that has been damaged by injury or surgery. When a problem develops somewhere, your body does the equivalent of calling 911. The alarm sounds, and the immune system springs into action. The first responders, the white blood cells, travel to the site of the problem. As weapons, some of the cells released a shower of powerful free radicals (called an oxidative burst) that aids in the destruction of invading microorganisms and damaged tissue.
Cats are true carnivores. While you may choose a vegetarian lifestyle, don't assume it's healthier for your cat also. Cats aren't able to convert beta-carotene into vitamin A the way we can. They must get vitamin A from animal tissue (called preformed A). Cats are also unable to convert linoleic acid (an essential fatty acid) to arachidonic acid the way dogs can so they must get preformed arachidonic acid from its only source-animal tissue.
So, what's the story?" "No story. Just a nightmare.' 'Meaning?' 'Meaning, heavy compression lines in his cartilage, severe bruising on his kidneys, liver and lower intestines. Fracture marks on his collar bone, tibia, radius, humerus, scapular, femur and every single one of his ribs have been broken. Don't even get me started on the concussive damage to his skull and brain tissue. Twenty-three percent of this boys body is scared for life. And yet, every organ is functioning normally and his neurological activity is above average. He's eighteen years old and he weights about two bills but remove the scar tissue and he'd weigh about a buck-ten. All in all, I say he lived inside a hydraulic car press, went through the Napoleonic wars and was on board the Hindenburg when it went down in flame and yet he's okay... this boy just refuses to die.
