	Male-Female Brain Differences What kind of brain do you have? There really are big differences between the male and female brain, says Simon Baron-Cohen, director of the Autism Research Centre, Cambridge University. In his new book, the Essential Difference: Men, Women and the Extreme Male Brain (published by Penguin) Baron-Cohen shows that, indisputably, on average male and female minds are of a slightly different character. Men tend to be better at analysing systems (better systemisers), while women tend to be better at reading the emotions of other people (better empathisers). Baron-Cohen shows that this distinction arises from biology, not culture. Cell numbers: men have 4% more brain cells than women, and about 100 grams more of brain tissue. Many women have asked me why men need more brain tissue in order to get the same things done. Cellular connections: even though a man seems to have more brain cells, it is reported that women have more dendritic connections between brain cells. Corpus collosum size: it is reported that a woman's brain has a larger corpus collusum, which means women can transfer data between the right and left hemisphere faster than men. Men tend to be more left brained, while women have greater access to both sides. Language: for men, language is most often just in the dominant hemisphere (usually the left side), but a larger number of women seem to be able to use both sides for language. This gives them a distinct advantage. If a woman has a stroke in the left front side of the brain, she may still retain some language from the right front side. Men who have the same left sided damage are less likely to recover as fully. Limbic size: bonding/nesting instincts - current research has demonstrated that females, on average, have a larger deep limbic system than males. This gives females several advantages and disadvantages. Due to the larger deep limbic brain women are more in touch with their feelings, they are generally better able to express their feelings than men. They have an increased ability to bond and be connected to others (which is why women are the primary caretakers for children - there is no society on earth where men are primary caretakers for children). Females have a more acute sense of smell, which is likely to have developed from an evolutionary need for the mother to recognize her young. Having a larger deep limbic system leaves a female somewhat more susceptible to depression, especially at times of significant hormonal changes such as the onset of puberty, before menses, after the birth of a child and at menopause. Women attempt suicide three times more than men. Yet, men kill themselves three times more than women, in part, because they use more violent means of killing themselves (women tend to use overdoses with pills while men tend to either shoot or hang themselves) and men are generally less connected to others than are women. Disconnection from others increases the risk of completed suicides.

	Top 10 brain damaging habits 1. No Breakfast People who do not take breakfast are going to have a lower blood sugar level. This leads to an insufficient supply of nutrients to the brain causing brain degeneration. 2. Overeating It causes hardening of the brain arteries, leadingto a decrease in mental power. 3. Smoking It causes multiple brain shrinkage and may lead to Alzheimer disease. 4. High Sugar Consumption Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development. 5. Air Pollution The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, bringing about a decreasein brain efficiency. 6 . Sleep Deprivation Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells. 7. Head Covered While Sleeping Sleeping with the head covered increases the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects. 8. Working Your Brain During Illness Working hard or studying with sickness may leadto a decrease in effectiveness of the brain as well as damage the brain. 9. Lacking in Stimulating Thoughts Thinking is the best way to train our brain, lacking in brain stimulation thoughts may cause brain shrinkage. 10. Talking Rarely Intellectual conversations will promote the efficiency of the brain.

	Pupula Duplex: Double pupil eye!!!! Pupula Duplex is a latin term which means double pupil. Its often referred by some by the following terms "evil eye", double iris and in medical literature as Polycoria. It is thought to be a condition where a person develops two irises, corneas and retinas on the same eyeball of each eye. It is really a mutation within th iris. This condition does not officially exist in official medical literature. Since there isn’t a great deal of evidence in the form of official literature supporting the existence of this condition, many people believe it is simply mythological It is often portrayed in science fiction literature. Although it is an extremely rare condition there are a few cases of famous historical figures who were born with this condition. The famous Chinese emperor Liu Ch'ung was featured on Ripley’s believe it or not as having had this condition. Read more about it : Link 1 and Link 2

	Human saliva contains a painkiller 6 times more stronger than morphine!! Human saliva contains a natural painkiller called opiorphin. Due to its powerful painkilling ability, scientists are trying to synthesize a new natural painkiller from opiorphin. It is great, because it doesn’t have the same addicting attributes that morphine does and would work better with the body. In a study, 1 milligram of opiorphin gave the same results as 3 milligrams of morphine did. In another study, involving rats standing on pins, they needed 6 times more morphine than opiorphin to make them oblivious to the pain. Opiorphin works in the nerve cells of the spine. It stops the usual destruction of natural pain killing opiates in the spine called enkephalins. It is such a simple molecule, that scientists believe it’ll be possible to synthesize it and produce large quantities of it without needing to isolate it from saliva. Another approach is to find a drug that will make the body produce more opiorphin to manage pain.
