Look younger,Feel younger & Stay young..



Keep always young. Youngness can your world green & more green.........
Look younger
A man typically greets those first wrinkles with an anxious frown, which in turn produces more wrinkles. Indeed, the effects of age first show up on our faces, especially around the eyes. In a recent study in Ophthalmology, 47 young adults had their eye movements tracked as researchers presented them with images of older adults. When asked to determine the ages of the people in the photos, the study participants focused on the eye region, particularly the brow and lower lids. If you want to fool the kids, the best thing you can do for your skin is to wear sunblock with an SPF of 30, says Cameron Rokhsar, M.D., a dermatologist and laser surgeon. The best block is Anthelios; it's the only sunscreen that contains mexoryl, a powerful drug that protects your skin against UVA rays. But that's just the start.


Stay young
If you want to see your 85th birthday, limit your alcohol to two drinks a day. This may make you less likely to die of cardiovascular disease, according to Japanese researchers. And make one of those drinks red. A recent review in Alcoholism: Clinical and Experimental Research suggests that resveratrol, a compound commonly found in red wine, may prevent or delay the onset of chronic disease. As you savor your pinot, swallow these other stay-young secrets.


Feel younger
Don't want to lose your marbles later? Lose some calories now. German researchers recently found that eating less can reduce markers of inflammation and insulin resistance, which are suspected risk factors for cognitive decline. Older study participants who cut 30 percent of their daily calories for 3 months were able to improve their memory on a word-recall test. Here are more ways to keep your youthful edge.

About phobia.........


About phobia.........

A phobia is a strong, persistent fear of situations, objects, activities, or persons.
The main symptom of this disorder is the excessive and unreasonable desire to avoid the feared subject. When the fear is beyond one's control, and if the fear is interfering with daily life, then a diagnosis under one of the anxiety disorders can be made.

Phobias are the most common form of anxiety disorders. An American study by the National Institute of Mental Health (NIMH) found that between 8.7% and 18.1% of Americans suffer from phobias.[2] Broken down by age and gender, the study found that phobias were the most common mental illness among women in all age groups and the second most common illness among men older than 25.

Causes
It is generally accepted that phobias arise from a combination of external events and internal predispositions. In a famous experiment, Martin Seligman used classical conditioning to establish phobias of snakes and flowers. The results of the experiment showed that it took far fewer shocks to create an adverse response to a picture of a snake than to a picture of a flower, leading to the conclusion that certain objects may have a genetic predisposition to being associated with fear.
Many specific phobias can be traced back to a specific triggering event, usually a traumatic experience at an early age. Social phobias and agoraphobia have more complex causes that are not entirely known at this time. It is believed that heredity, genetics, and brain chemistry combined with life-experiences play a major role in the development of anxiety disorders, phobias and panic attacks.

Treatments
Various methods are claimed to treat phobias. Their proposed benefits may vary from person to person.

Some therapists use virtual reality or imagery exercise to desensitize patients to the feared entity. These are parts of systematic desensitization therapy.

Cognitive behavioral therapy (CBT) can be beneficial. Cognitive behavioral therapy lets the patient understand the cycle of negative thought patterns, and ways to change these thought patterns. CBT may be conducted in a group setting. Gradual desensitisation treatment and CBT are often successful, provided the patient is willing to endure some discomfort. In one clinical trial, 90% of patients were observed with no longer having a phobic reaction after successful CBT treatment.

Research on Brain Development Is Important for Parents


Brain cells are “raw” materials — much like lumber is a raw material in building a house. Heredity may determine the basic number of “neurons” (brain nerve cells) children are born with, and their initial arrangement, but this is just a framework. A child’s environment has enormous impact on how these cells get connected or “wired” to each other. Many parents and caregivers have understood intuitively that loving, everyday interactions — cuddling infants closely or singing to toddlers—help children learn.

A brain is not a computer. The brain begins working long before it is finished. And the same processes that wire the brain before birth also drive the very rapid growth of learning that occurs immediately after birth. At birth, a baby’s brain contains 100 billion neurons, roughly as many nerve cells as there are stars in the Milky Way. Before birth, the brain produces trillions more neurons and “synapses” (connections between the brain cells) than needed. During the first years of life, the brain undergoes a series of extraordinary changes. Then, through a process that resembles Darwinian competition, the brain eliminates connections that are seldom or never used.

“Windows of opportunity” are critical periods in children’s lives when specific types of learning take place. For instance, scientists have determined that the neurons for vision begin sending messages back and forth rapidly at 2 to 4 months of age, peaking in intensity at 8 months. It is no coincidence that babies begin to take notice of the world during this period.

Scientists believe that language is acquired most easily during the first ten years of life. During these years, the circuits in children’s brains become wired for how their own language sounds. An infant’s repeated exposure to words clearly helps her brain build the neural connections that will enable her to learn more words later on. For infants, individual attention and responsive, sensitive caregiving are critical for later language and intellectual development.

Research does not suggest drilling children in alphabet songs from different languages or using flash cards to promote rote memorization of letters and numbers. Children learn any language best in the context of meaningful, day-to-day interactions with adults or other children who speak the language.

Schools can take advantage of this window of opportunity to teach language. If children are to learn to speak a second language like a native, they should be introduced to the language by age ten.

Early stimulation sets the stage for how children will learn and interact with others throughout life. A child’s experiences, good or bad, influence the wiring of his brain and the connection in his nervous system. Loving interactions with caring adults strongly stimulate a child’s brain, causing synapses to grow and existing connections to get stronger. Connections that are used become permanent. If a child receives little stimulation early on, the synapses will not develop, and the brain will make fewer connections.
