Health benefits, you're agreeing increasing age

Health benefits, you're agreeing increasing age - Most people are worried about old age is more attractive because of its appearance and movement of ideas that parents synonymous with "sick" word. But age does not always go bad and even offers a variety of health benefits.

When parents age, someone thinks would be more mature and avoid stress these things. So do not be surprised if a large number of middle-aged people reported that their quality of life improved and happier.

Here are six health benefits that you can gain with age, among others:

1. Rarely flu
Compared to when you were a child or a teenager, you seldom flu at the age of age. Person's immune system is weakened by age, but research shows that the body is even more powerful in the fight against infection at the age of 30-40 years.

Over time, the body will store more types of different antibodies. Years later, when you're new influenza virus similar antibodies is a powerful tool to prevent recurrent infections.

2. Endurance is primed
A study shows that a woman's body reaches peak fitness at the age of 35 years. "Women have the ability to maintain the fuel of the body, especially fat very effective," wrote Pamela Peeke, MD, in his book "Body For Life For Women.

So it is not surprising that so many runners who have achieved success at a young age is no more. This is because mentally healthy in old age, which makes the body more excellent stamina.

3. High sexual satisfaction
Shift the balance of hormones when someone was in her early 40s
years, can actually increase sexual desire and the ability to have an orgasm. In addition, the body will feel more comfortable making love and trust more the pair, so as to promote sexual satisfaction.

According to the survey, only 61 percent of women aged 18 to 24 who have had an orgasm during their last sexual intercourse. Compared to 65 percent of women in their 30s and 70 percent of women aged 40 to 50 years.

4. Require much less maintenance
When parents age, it is normal lines or wrinkles that appear on the face. But at an advanced age, require less maintenance ubuh you when you were young. The scalp of the person to produce less oil as you age, so hair is not easy to get dirty.

The rate of hair growth may also decrease because estrogen levels are low ore, so that you do not need a haircut as often. Hormone levels more stable also makes women avoid acne problems in the elderly.

5. The stress level
At a young age, a person will be filled with anxiety such as salary, work environment, cost of living, family, school fees and so on, where there is no longer cause anxiety in ancient times.

Aging makes a person more easily experience the joy of escaping the responsibility of caring for children who have grown up, the work that has been put in place, trust and loyalty partners will.

6. The increase in mental abilities
Obviously, the higher the age, it will be more forgetful, but a new study shows that some mental abilities can be improved when a person reaches middle age. This is known as "neuroplasticity," the ability to learn from the experience of life.

Studies have shown that we begin to use both sides of the brain to manage routine tasks, making it easier to solve the problem, which could explain why someone age 40 to 50 years had higher scores on cognitive tests

Medical ultrasonography

Medical ultrasonography - Typical ultrasound diagnostic scanners operate in the frequency range of 2-18 MHz, although frequencies up to 50-100 MHz has been used experimentally in a technique known as biomicroscopy in specific areas, such as room front of the eye. [Citation needed] The choice of frequency is a compromise between spatial resolution and imaging depth photo: lower frequencies produce less resolution but image deeper into the body. The sound waves of higher frequencies have wavelengths which are smaller and therefore capable of reflecting or scattering of small structures. The frequency of sound waves higher has a larger attenuation coefficient and thus more easily absorbed in the tissues, which limits the depth of penetration of the sound waves into the body.

Ultrasonography (ultrasound) are widely used in medicine. It is possible to perform the diagnostic and therapeutic, using ultrasound to guide interventional procedures (for example for a biopsy or drainage of fluid collections). Sonographers are professionals who perform scans are then generally interpreted by a radiologist, a physician who specializes in the application and interpretation of a variety of medical imaging modalities, or by Cardiologists in the case of cardiac ultrasound (echocardiography). Sonographers typically use hand-held probe (called a transducer) that is placed directly and moving patients. Increasingly, clinicians (physicians and other health professionals who provide direct patient care) to use ultrasound in their office and hospital practice, for efficiency, inexpensive imaging, diagnostic dynamic facilitate treatment planning, while avoiding exposure to ionizing radiation.

Effective body ultrasound imaging of soft tissue. Surface structures such as muscles, tendons, testes, mammary glands, thyroid and parathyroid and the neonatal brain are imaged at a higher frequency (7-18 MHz), which provides better axial and lateral resolution . Deeper structures such as the liver and kidney are imaged at a frequency of 1-6 MHz below the lower axial and lateral resolution, but penetration.

Produce sound waves
A sound wave is typically produced by a piezoelectric transducer encased in a housing which can take several forms. Strong, short electrical pulses from the ultrasonic transducer to the ring at the desired frequency. The frequency can be anywhere between 2 and 18 MHz. The sound is carried either by the shape of the transducer, a lens on the front of the transducer, or a complex set of control pulses of the machine ultrasonic scanning (beamforming). This orientation produces a sound wave in form of an arc of the transducer face. Wave propagates in the body and is developed to a desired depth.

Transducers older technology focusing the beam with lenses physical. Newer technology transducers use phased array techniques to enable ultrasound machine to change the direction and depth of field. Practically all piezoelectric transducers are made of ceramics.

Materials on the face of the transducer to enable the sound transmitted efficiently in the body (generally appears to be a rubber layer, in the form of impedance matching). In addition, water-based gel is placed between the patient's skin and the probe.

Sound waves partially reflected from the layers between different networks. More specifically, the sound is everywhere where there are density changes in the body: eg blood cells in blood plasma, small structures in organs, etc. Some of the reflections return to the transducer.
