Doing this 4 steps, risk of dementia will be reduced!

The average of human life is rising from time to time. However, the risk of getting dementia among human is getting higher and affect their life. If everyone wants to live long with good quality of life, he or she must move a lots and train their brain regularly. So exactly what is dementia?

Dementia

For completing an action, we need our brain to think about things we need to be done and action with our psychomotor. If our mind cannot receive or process information, we call it cognitive decline. Therefore, when talking about dementia, we are talking about a person whose cognitive function gradually declines compared to a few years ago or a few months ago. Remember, this does not just mean that this person has a bad memory!

In fact, dementia will reduce a person's ability to use language, or a person's attention, judgment, planning decision-making process and execution ability. As long as the cognitive declines affect daily life, it is considered dementia. When dementia becomes more serious, the patient may cannot control his emotions. His personality will change, and he may even lose the ability to take good care of himself. 

① Take care of blood vessels

First of all, when we talk about many brain problems, we will say that "repeated stroke" is very harmful to the cerebrovascular. Therefore, it is important to change and reduce the factors that can easily cause stroke. And the most important of these is that the brain will be healthy only if the blood vessels are taken care of. If the blood vessels are not good, it may become clogged and the blood cannot flow through; or the blood vessels may rupture and cause intracerebral hemorrhage. Either way, it will greatly damage the health of brain cells. After a stroke, the cognitive function of the patient will decline.

Therefore, if you want a healthy brain, you must take care of your blood vessels and control the three highs. To control the three highs, in addition to taking medications according to the doctor’s recommendations, you must also adjust your lifestyle, maintain a proper weight, and don’t burden your body too much.

②To be active

Next, if you want to avoid dementia, you must be active in joining activities such as physical activities, mental activities, and social activities. Physical activity can be the easiest way where you can do it at home. You can do gardening and household chores, don't sit on chair or  lie on bed for long time, stand up and walk around. Go for a walk in the park to exercise. If the body can afford it, practice some weight training to build up muscles and avoid sarcopenia, so that the body can get healthier. Being active in the mind means not watching TV or chasing dramas all day long. When watching TV, it is mostly “passively receiving information”, but there is no time for brainstorming. Find some time to use your brain every day by playing with educational toys, solving math problems, solving puzzles, and playing crosswords in newspapers are all good ways for brainstorming. The last one is you need to be active social activities as it involves our brains actively in receiving, processing and delivering the information.

③Eat healthy and nutritious

When we having three meals a day, we have to choose carefully on types of food that is good for our health Food choices are very important in supplying the nutrients and minerals that need by our body. Modern people are well-nourished as they take in nutrients from healthy foods and make them balanced. Although seasoned food is delicious, but it is not good for health! If you want to eat healthy, you have to eat as many types of food as it is, and don’t cook food at too high a temperature. Besides that, brown rice will be better than white rice, and freshly cooked chicken will be better than processed red meat.

④ Sleep well

Everyone must have this kind of experience where you didn't sleep well the day before and lack of sleep causes you couldn't do anything the next day, and became very irritable. If someone asks a harmless sentence, you will get angry. In fact, poor sleep and insufficient sleep are very harmful to the brain. Because sleep is the key time for the brain to remove wastes. If you sleep well, the wastes can be eliminated and will not stay in the brain. According to the health research, people with sleep disorders have a high chance of developing cognitive deterioration or Alzheimer's disease in the future. Although you are young,  please don’t think that it’s okay to be tired. If you don’t sleep well at the age of 30 or 50, you will accumulate more risk of dementia in your body.

未来十年，最容易被淘汰的9种人！

未来十年，最容易被淘汰的9种人！

学习呢，是一个长久的过程。我们人是需要通过不断学习，不断追求知识而跟上时代的脚步。就好像所谓的优管主播，因为著名主播公开通过视频而赚取高收入后吸引了一些新一代年轻人纷纷加入并开始制作视频。在这种密集的竞争下，很多人不是以非正规手段来制作视频，不然就是直接放弃。很多人放弃的时候并没有真真地去学习，去了解优管的条例与本身不该触犯的禁忌。

生活也是很多人因为站稳了舒适圈以及个性懒散而拒绝改变，或浑浑噩噩地过日子。这些人并没有活得一天比一天更加进步。在这种通讯广泛，科技发达的时代，我们本身若不在努力提升本身的能力或知识，我们很快就会被社会嫌弃并抛于千里之后。那么今天我们就谈谈在未来十年内，哪些人最容易被淘汰?

①8小时外不学习的人

人与人直接的区别就在于一个人如何有效地使用一天的时间。假设每个人一天最高效率的时间为八小时，那么每个人的高低就取决于如何运用这八小时。若人们有效地使用这八个小时决定现在，那么这八个小时将报答你的未来。一个人通过有效率地学习得到知识以及技能，我们人才会有选择权。

②对新生事物视而不见的人

在科技发达的时代，任何一个新事物的诞生都与成功的机会有密不可分的关系。就好像当下新冠病毒袭卷全世界，很多公司或小贩都需要认真地去看待新事物、新平台来维持生机。比如行动管制下，很多公司、小贩、商家都纷纷关门大吉，因为他们并没有跟上变化并看待新事物的出现。他们其实可以通过网络虚拟店去售卖货物如shopee或lazada, 通过直播售卖，代步软件等等。我们需要知道新事物往往与趋势有关，趋势不是当靠我们眼睛来看，而是要用我们的眼光来判断的。若我们继续对新事物视而不见、充耳不闻，不跳出舒适圈去学习新事物，最终我们一定会被淘汰。

③靠个人能力单打独斗的人

在这竞争强力的时代，一人的能力往往有限抵不住竞争对手千千万万的战力。21世纪是英雄退位、团队晋位的时代。一个团体打天下已经是大势所趋，就好像优管平台，很多新生代网红都是以一个团队磨合达到共识并走得久远。小编本身看到坚持最久的团队有我们这群人（youtube),五月天(音乐）以及其他等等。俗语说得好，一根筷子易折断，十双筷子难折断。

④玻璃心、心理脆弱易受伤的人

事情的大小不重要，你的想法很重要。很多事情本身并不伤害你，反而本身的想法却是伤害你最深的元凶。就比如在《你好对方辩友2》中一个角色名叫陶好，也是因为个人的想法而导致自己本身受到了极大的伤害。个人想法往往是导致一个人情绪不受控制而抑郁。人嘛，为何不看开一点，别多想呢？《小胖流浪记》中的小胖也说过：“人生短短几十年，不给我打game，还有什么意思？！”我们人短短几十年，为何要因为一些言论，一些失败而搞得自己不开心呢？加油吧读者们，笑一个！

⑤技能单一，没特长的人

现今的社会，很多行业、很多工作不断地被淘汰、不断地被机器人取代。这是因为我们人的能力、体力、精神力都不如机器来得可靠。很多人在舒适圈呆太久后也渐渐忘了危机感。但，往往没有危机感的人才是最高几率遇到危机的目标。人一定要在得意的时候，时时给自己找出路，不要等失意的时候才来想办法。那个时候已经为时已晚，切记！

⑥计较眼前，目光短浅的人

计较眼前会失去未来，计较小钱会失去大钱。现今的社会最好的投资就是投资学习，最没有风险的投资依然是投资学习。学习可以让人有远见，只有通过学习才能知道未来的趋势。也只有学习，我们才能将我们所学，所知变现。

⑦情商低下者

通常说女人翻脸比翻书还快，错！！现代人都是如此，因为情商往往在人们追求财富的途径上就被抛于脑后。大家要记得脾气来了，福气也跟着走了。IQ（智商）高可以找个好工作，EQ（情商）高可以拥有未来，AQ（逆境商）高可以变成登峰造极的人。若你想要在这竞争力强的时代站稳脚跟，任何一个都不能抛弃。

⑧观念落后，知识陈旧的人

过期的食品不能吃，过期观念也不能用。21世纪的成功学，不是你能赢过多少人，而是你帮助过多少人。学会主任成功的本领。世界上最大的敌人不是别人，而是自己。

⑨坐而论道，不善行动的人。

一个行动远胜与十二大纲领。坐着谈，如何起来行，世界上没有十分把握，只有十分的行动。机会永远留给有准备的人，更留给善于行动的人。

Is donating blood good or bad for the body?

 Is donating blood good or bad for the body?

From time to time, I can always met some news about "The blood bank is ischemic, the patient is in danger, and the patient in urgent need of XX type of blood, people who caring those blood type please come to donate blood"

But in fact, once it has been widely publicized by the media that blood stocks have been warned.

Unpaid blood donation should be normalized. When there is an emergency in the blood bank, it means that there is not enough blood for clinical use, and it need some time for media to advertise it and  need to wait for people to donate. During the waiting period, the patient may be in danger at any time.

But when some blood donation even carry out in certain places such as shopping mall, the event always being reacted coldly by the public. Part of the reason is that everyone is always frightened about blood donation. There will be various questions such as "Will donating blood affect the body?" "Will donating blood cause obesity?"

So today, we are going to talk about these.

The so-called blood donation is to temporarily store the blood of healthy people for use by patients who need blood transfusion.

How much blood is in the human body?

The total blood volume of a normal person is equivalent to 7%-8% of body weight. Most of this blood rushes and circulates in the cardiovascular system, which is called circulating blood volume; a small part is retained in the liver, lungs, abdominal vena cava, subcutaneous vein and other places to prepare for rapid replenishment of circulation in critical situations such as massive bleeding. Blood volume. However, there is a limit to "just in case". If the patient loses 20%-25% of the blood in a short period of time, or there are blood diseases such as leukemia, blood problems will be induced and blood transfusions must be performed.

What is blood transfusion?

Blood transfusion is the blood components, namely plasma and blood cells.

The main component of plasma is water, followed by gases, electrolytes and small molecular organics. In addition, it also contains a certain amount of protein. Blood cells are constantly circulating, carrying out a "reconstruction-destruction-reconstruction" cycle. White blood cells, red blood cells, and platelets all have a certain life span, and the cycle of birth, aging, and death continues.

Secondly, the dose of blood donation (200ml, 400ml) is very low, far from reaching the 20%-25% warning line; healthy people are fully capable of recovering in a short time.

So what are people worrying about donating blood?

NO 1: Does blood donation affect immunity?

wrong.

The human body's immune system mainly includes three parts: a barrier composed of skin and mucous membranes, an innate defense system composed of phagocytes, and an acquired immune system composed of B cells and T cells. Phagocytes, B cells, and T cells are all white blood cells. White blood cells have a certain lifespan. After a certain period of time, the human body will destroy the white blood cells. At the same time, the bone marrow and other hematopoietic tissues are producing new white blood cells every moment.

Therefore, blood donation will not affect immunity.

NO 2: Donating blood may cause fainting?

Correct.

Blood donation may indeed cause fainting, which is often referred to as a blood donation reaction. In addition to fainting, blood donation reactions can also cause symptoms such as nausea, vomiting, pale complexion, palpitation, cold sweats, and chest tightness. However, overall, the incidence of blood donation reaction is very low, and it can be prevented with minor consequences. After receiving care, the patients returned to normal within a few minutes.

NO 3: Can't donate blood for high myopia?

Controversial.

Old version of the "Blood Donor Health Examination Standards" implemented in October 1998 stated that "patients with ophthalmological diseases, such as keratitis, optic neuritis, and high myopia with changes in the fundus," cannot donate blood.

However, the latest version of the 2011 "Blood Donor Health Examination Standards" has been revised, this part has been deleted, and it has been changed to "Those with active or progressive eye diseases who have recovered less than one week after the eye surgery. Those who have been 3 months old are listed as those who cannot donate blood temporarily.

Compared with normal people, patients with high myopia (greater than 600 degrees) have thinner blood vessels in the fundus, and blood flow is also reduced. Since the blood vessels of the human body are connected to each other, a slight change in blood pressure after blood donation may affect the blood vessels of the fundus, causing vasospasm of the fundus and the risk of retinal detachment.

Therefore, it is not high myopia that affects blood donation, but changes in the fundus. Although high myopia has a high probability of changing the fundus, it is not the only cause of abnormal fundus. If possible, it is best to perform a fundus examination before blood donation; if there is no condition and it happens to be high myopia, then, to be on the safe side, it is fine to not donate.

NO 4: Multiple blood donations will lead to obesity, blood pressure and other problems?

wrong.

After a single blood donation, the human body can recover quickly. The Red Cross, the government and other blood donation management organizations have also made strict regulations on the blood donation interval, leaving a sufficient recovery period for volunteers. In theory, multiple blood donations will not have an adverse effect on the human body.

In conclusion, blood donation has no long-term damage to healthy people. Blood is a precious medical resource. Guard your city. Don't wait for the blood bank to be in a hurry before donating blood. Let our city, 365 days, uninterrupted blood!

华人传统观念：拿开水烫筷子，能够尽到消毒的功用。这么做真的有用吗？

华人传统观念：拿开水烫筷子，能够尽到消毒的功用。这么做真的有用吗？ 

筷子是华人最常用的餐具之一。筷子起源于中国，古代叫箸（箸者，助也，意思是帮助吃饭的工具），也叫筯。因“箸”与“住”字谐音，“住”有停止之意，乃不吉利之语，所以，就反其意而称之为“筷”。这就是筷子名称的由来。

很多人在外用餐时都会有一种习惯，那就是用开水烫筷子、碗碟等餐具。因为公共使用的餐具，大家都希望通过开水烫餐具能进行一定功效的消毒。我相信在荧幕前面的你也是如此吧～～

那么问题来了，用开水烫餐具真的能起到杀菌、消毒的作用吗？

为了帮助消费者了解筷子为什么会发霉以及筷子有效的消毒方法，近日，上海市消保委委托品测（上海）检测科技有限公司便开展了专项测试。

在本次测试中，上海市消保委收集了200双普通家庭使用过的旧筷子和660双新筷子。其中筷子的样品材质包括了木、竹、不锈钢、密胺、合金等五类。

测试结果显示，湿筷子的霉菌比干筷子多25%以上。霉菌在湿度80%的条件下（如南方地区的梅雨季节）极易生长，而在湿度40%的条件下基本不生长。温度对霉菌生长的影响不大。

另外，筷子使用时间超过6个月更容易长霉，霉菌数量会比新筷子和使用了3个月的筷子要多30%以上。

木质和竹质筷子结构疏松，表面的凹槽、细纹容易藏匿细菌。竹木筷的霉菌数量反而是不锈钢、合金、密胺筷的7倍以上。

除此之外，测试结果还显示了酒精对霉菌基本没有作用；微波炉虽然消毒时间最短（3分钟），但只能用于合金筷；五类筷子都可通过高压锅、沸水、臭氧消毒柜来消毒，只是所用消毒时间略有差异。

值得注意的是，“用沸水烫一下筷子”的做法基本没用，只有当消毒时间超过20分钟，筷子上的菌落和霉菌才能被有效去除。五类筷子中，不锈钢、合金、密胺筷更易消毒，木筷、竹筷稍差。

上海市消保委还提醒各位消费者，筷子存放的地方一定要注意保持环境干燥。筷子只有在湿度大时极易发霉。生活在湿度大的环境的消费者呢，如梅雨季，建议用除湿机降低室内空气湿度以防止发霉。

最后，筷子最好每周进行一次消毒，养成勤换筷子的习惯，最好半年换一次这样才能阻止霉菌的滋生。
