Why do many elderly people still use feature phones?

<> there was an old man playing an erhu in the underground passage.

A small stool, an erhu, and a bottle of mineral water are all his trades. I'm not an expert, I don't know if he pulls well or not, I just see how intoxicated and engaged he looks. I often close my eyes, shake my head, and shake my whole body in the excitement.

Passers-by hurried, rarely stopped, most of them took a look, and continued on their way.

There are also a few ones, pause, look at it, listen to a few paragraphs, and then slowly go away. There was no cup or bowl in front of the old man, so no one threw away a small amount of money, but there were also people who didn't know what to do, and they left a steel collapse far away, making a crisp sound of "dripping spirit". At this time, the old man opened his eyes half-awake and half-closed, and closed them again, and the erhu in his hand still did not stop.

After a few days, a wooden board was erected on the wall behind the old man, which read: "Entertain yourself, do not give alms." "However, there are still careless people, and from time to time there will be the sound of steel crashing.

There are also good people who ask the old man: Why do you come here to play erhu? The old man said

At home, everyone in the family is annoying, and the neighbors also have opinions. It was found by chance that pulling in the underground passage worked particularly well.

And so it opened. "It's right to think about it, there are not many living rooms now, and the sound of the erhu penetrates the room, which will definitely affect other people's learning and rest. It's okay to do it occasionally, but it's inevitable that there will be no opinions in the long run. And the underground passage is warm in winter and cool in summer, so there is no need to use it in vain.

After some time, when I passed by, I noticed that the words on the wooden board beside the old man had changed, and it read: "To give or not to give, listen to the convenience." Don't thank you for giving, don't blame for not giving.

A plastic basin was placed in front of him, and under the basin was a piece of blue calico. Someone asked him, how did he have such an idea? The old man said

I don't want it, others want to give it. Instead of twisting and pinching, it's better to mix two wine money! ”

There are many factors to consider when choosing hearing aids for the elderly, in addition to the hearing condition of the elderly themselves, it is also necessary to consider whether it is convenient for the elderly to operate, and some elderly people also have requirements for the appearance of hearing aids. For the choice of behind-the-ear machine and customized machine, they have their own love. Understand the characteristics of behind-the-ear machines and customized machines to better choose the right hearing aids.

Advantages of the behind-the-ear machine:

2. Behind-the-ear hearing aids are larger and suitable for various types of hearing loss. Due to the large size of behind-the-ear hearing aids, designers can easily install some complex wiring chips to improve performance and enhance functionality.

3. The battery, knob, etc. are large and easy to operate. Easy to repair, durable, easy to adjust.

Advantages of customized machine::

1. The ear canal hearing aid can completely design the shell and ventilation hole of the hearing aid according to the patient's hearing curve, so it can achieve clearer hearing and less noise.

2. The ear canal hearing aid is customized according to the patient's ear canal, so it is very convenient and comfortable to wear.

3. The hearing aid is placed in the ear canal, which maintains the natural characteristics of the pinna to collect sound, making the sound of listening more natural, and the sweat is not easy to invade. It is especially suitable for patients with sensorineural hearing loss.

Is it better for the elderly to have a behind-the-ear machine or a customized machine? This depends on the specific situation.

For the elderly to buy hearing aids, it is usually recommended to choose behind-the-ear hearing aids, the elderly are generally moderately and severely deaf, and the power of the behind-the-ear machine is generally larger, which is suitable for patients with moderate to severe deafness.

Modern immunology proves that when people sleep, the body will produce a sleep factor called muramic acid, which can promote the increase and activity of white blood cells and macrophages, improve phagocytosis, and it can also enhance the function of the liver and spleen, thereby helping to destroy bacteria and viruses that invade or enter the human body. University of Florida in the United States to immunologist Berry. The scientific research team led by Professor Dabi has done research on the relationship between sleep and human immunity, and experts have conducted self-hypnosis training on 28 test subjects, and the results are:

The results of this study are of great significance for understanding that adequate sleep can help improve the body's immunity and disease resistance.

Due to the aging of tissues and organs and the deterioration of functions of the elderly, the immunity will be at a low level, and the ability to resist diseases will decrease; In addition, the pineal gland in the brain, which coordinates the relationship between day and night, shrinks, and the sleep rhythm is disturbed, making it difficult to get enough sleep, so that the body does not get enough rest, which will affect their immune function. The elderly are susceptible to colds, pneumonia, urinary tract infections, cardiovascular and cerebrovascular diseases and cancer, mainly due to the continuous weakening of their immunity. Therefore, during the epidemic of infectious diseases, such as influenza and atypical pneumonia, special attention should be paid to and attention to the elderly, and sleep *** helps to improve the body's immunity, so sufficient sleep time should be ensured every day.

Studies at home and abroad have confirmed that sleep disorders are one of the important factors that trigger the decline of the body's immunity. Lack of sleep can lead to the attenuation or decrease of the activity of neutrophils, phagocytic cells, NK cells, etc., and can also make antibodies not only easy to induce infectious diseases such as colds and pneumonia, but also prone to neurasthenia, hypertension, coronary heart disease, cancer and psychological diseases. A study also pointed out that no matter what the cause of sleep deprivation is, the result of weakened immunity is the same, people with apnea syndrome, the risk of stroke is 3 times that of normal people, the probability of heart disease is also greatly increased, if you sleep only 4 hours a night, the secretion of insulin will decrease, and the symptoms of prediabetes will appear within 1 week.

A study in the United Kingdom showed that poor sleep habits can lead to infections, depression, diabetes, obesity, stroke, heart and encephalopathy and cancer, in addition to regular sleep deprivation can also induce mental confusion.
