From Michael Phelps to business lesson

The rules that make Michael Phelps the most Olympic medalist in history will also help you win the marketplace.

Becoming a business owner is like becoming a professional athlete. You must have strict discipline in managing your own time and resources. You have to be really calm to face the pressure of giving presentations to investors or advising difficult clients. And most importantly, you must be highly focused on achieving the goals you have set for yourself and your company.

So, what athletes can do all of the above?

That is Michael Phelps.

At the end of the 2016 Olympics held in Rio de Janeiro, Phelps brought 5 gold and 1 silver medal to the United States. This achievement also brought the total number of medals he won to 28 (including 23 gold), something no one else in history has done. Phelps also announced that this is his last Olympics. However, I do not know if this is true because, after the end of the 2012 Olympics in London, he said the same thing.

Regardless of whether Phelps will retire in the next Olympics, here are three pocket things you can learn from him.

1. Let challenges lead you to success

An article on the site said Phelps was diagnosed with attention deficit disorder (ADD) as a child. Therefore, swimming has been recommended by the doctor to the Phelps family as a remedy for this. No one expected that when the boy Phelps started swimming at the age of 7, one day he would break a series of records to become the most successful Olympic athlete of all time.

In 2014, Phelps was arrested for driving while drunk, which forced him to find a way to quit drinking and take a strict self-examination. An article by the Baltimore Sunsaid that after going through that incident, he “raised his love of work to a new level”. And when village coach Bob Bowman visits Phelps in a re-education center in Arizona, he finds that he “seems determined to have to deal with the darkest patches of his past”.

As a business owner, sooner or later you will find yourself falling into unintended adversity. Successful people move forward in the midst of challenges, and turn transient failures into spark that ignites the desire to win ultimately.


Things to know about first aid for drowning (Part 2)

2. Things to avoid when drowning

Most victims of asphyxiation when taken to the emergency department of hospitals do not receive first aid or improper first aid resulting in death or brain sequelae due to lack of oxygen. Incorrect first aid methods include:

– Spending a lot of time on the water shock: the upside down movement is unnecessary and should not be done because often the amount of water entering the lungs is very little, not the lungs filled with water like people think. This very small amount of water is expelled when the victim breathes again. In addition, flushing also slows down the emergency time and increases the risk of choking.

– Roller roll: for children to lie on their stomach on a pot to let the burning straw inside roll back and forth in order to “drain the water” in the child’s body. This method is ineffective, and also causes burns to the child.

– The victims of cardiac arrest apnea are not given first aid to suffocate and press the heart at the place where the accident occurred or while transporting the victim to the medical facility. This causes the brain and organs to be chronically deprived of oxygen, brain cell death leads to death and severe brain sequelae. So, it is best to have ambulance as soon as possible to get the victim’s head out of the water before bringing it ashore.

3. The following factors increase the risk of asphyxiation

  • Can’t swim or appreciate his swimming ability.
  • Risky behaviors such as bathing in the river, playing on the banks of lakes, …
  • Lack of adult supervision.
  • Hypothermia leads to rapid exhaustion and inability to swim.
  • No primary arrhythmia was detected.
  • In older children it can be caused by drinking alcohol, drug use …
  • Injury, cerebral vascular accident , myocardial infarction .
  • Increasing ventilation before jumping into water reduces PaCO2, while PaO2 decreases to 30-40 mmHg due to consumption. Because the PaCO2 is reduced, it does not stimulate respiration. This causes cerebral hypoxia, convulsions, loss of consciousness leading to drowning.

Things to know about first aid for drowning (Part 1)

Drowning is a form of asphyxiation, caused by water being inhaled into the lungs, or blocked airways from spasm of the larynx while the victim is in water. This is a common accident that occurs while swimming, boating and during water activities. However, it can also happen at home such as in a water tank, a jar, a drain, etc.

When suffocated, the victim stops breathing, the heart beats slowly due to reflexes. Apnea continues to lead to hypoxia, increasing heart rate, and blood pressure. If breathing stops persist for about 20 seconds to 2 – 5 minutes (depending on the victim), the threshold is reached and the breathing reappears, causing water to be inhaled causing immediate laryngospasm. second breath apnea followed by forced breathing breaths causing water and foreign objects to be inhaled. As a result, the heart rate slows down, arrhythmia, cardiac arrest and death.

1. How to first aid drowning

First aid in place and the right technique is the most important, determining the survival or sequelae of the victim’s brain.
In order to save the life of a suffocated victim, the above processes must be promptly stopped, preferably right from the first stop of breathing, i.e. within the first 1- 4 minutes of being submerged in water, and handling well. comorbid injuries (especially head, neck and spine injuries ).

The correct first aid method is as follows:

  • Quickly remove the victim from the water surface by holding the victim’s arm, long pole to grasp, tossing the victim or picking up the victim.
  • Place casualty in a dry, well-ventilated place
  • If the victim is unconscious, check if the victim is still breathing by observing the movement of the chest:
    + If the chest is not moving, the victim is not breathing, perform the cardiac out of the chest half. under the sternum. Combine cardiac pressure and asphyxiation at the rate of 15/2 (2 ambulance) or 30/2 (1 ambulance) for 2 minutes and then reassess if the victim is breathing again? Are lips pink? Is there a reaction when shaking stimulates pain? If not and must continue these emergency operations even on the way to transfer the victim to a medical facility.
    If the victim is still breathing on his or her own, place the victim in a safe position lying on his side so that the vomit can easily escape if the victim is vomiting.
  • Remove wet clothing and keep warm by covering the victim with a blanket or dry towel
  • Promptly bring victim to a medical facility even if the victim appears to be normal or recover completely from first aid as the risk of secondary dyspnea can occur several hours after suffocation

5 reasons why we should know how to swim

Science has shown why we should go into the water and swim for its exceptional benefits.

1. Swimming is good for the lungs

When your face is underwater, oxygen is at a high level. Your body will adapt to use oxygen more efficiently. Plus, it will learn to breathe in cleaner air with each breath and release more C02 with each exhale.

A study in the Indian Journal of Physiology and Pharmacology also found that swimmers have better heart rates than runners. This means they have lower blood pressure and will function better.

2. You will run better

By increasing your ability to absorb and use oxygen efficiently, swimming increases your stamina.

According to the 2013 Journal of Sports Medicine and Science, controlled swimmers improved running performance by 6% after just 12 swimming sessions.

3. Helps reduce stress

Your stress level will decrease when you go into the water to exercise. According to research published in Pain Research & Management, being submerged in water really feels calm and relaxed.

4. You could be smarter

According to a study in the Journal of Physiology, blood flow to the brain increases up to 14% when the body is submerged in water. Researchers believe that the pressure of water on the chest cavity may be related to it, and they are currently investigating whether water exercises improve blood flow to the brain better than the upper exercise. ground or not.

5. Swimming offers a great experience

Swimming is a life skill and it opens many interesting doors. Mastering swimming will help you have a great experience when it comes to participating in better water activities more easily.

Swimming is also a sport that causes little injury to the body, very suitable for people who cannot do some form of intense exercise. You should be able to swim because you may have to use your technique to save people or simply participate in fun with friends and relatives.

Estimates are not just for free swimming. Normally, swimmers will burn the same amount of calories when doing backstroke versus slow freestyle swimming, according to Nutristrargety.

Swimming an frog for an hour will burn the same amount of calories to perform a quick free swim.

However, swimming butterflies burn the most calories. Calorie burning levels range from 649 calories for a person weighing 60 pounds to 1,024 calories for a person weighing 90kg.

11. Diverse and fun

People tend to get bored with repetitive exercise, but swimming has many different forms to make it fun.

There are several types of swimming or float methods you can try. In addition, underwater aerobics and polo classes, as well as racing and diving, can help to add a variety of options.

If you want to sleep more, try swimming more often. Some researchers and fitness enthusiasts have agreed that exercise, such as swimming, has the potential to help solve this problem, according to the US Centers for Disease Control and Prevention. About 50 to 70 million Americans have sleep problems and, in addition to the short-term side effects that anyone does not get a good night’s sleep – such as difficulty concentrating or remembering things, staggering, baggy eyes – Not getting enough sleep can have long-term health consequences. Lack of sleep has been linked to obesity, diabetes, depression and hypertension.

13. Improve mood

Exercise releases endorphins, which help improve mood. Swimming can also boost confidence and social skills, which can affect a person’s self-esteem.

A 2014 pilot study involving people with dementia found that people who swam often for 12 weeks showed improved mood.

14. Control stress

Exercise is a great way to reduce stress and anxiety. It can also turn the mind away from troublesome thoughts.

Although more research is needed, even 20 minutes of physical activity per week can help you feel more relaxed.

15. Easy to access and affordable

If in the countryside, you can swim for free at the pond, lake or the sea. But remember, always take safety precautions, such as making sure someone is supervised, when swimming in places like this.

If in the city or town, the payment to swim in the pool is not high. Some pools are free at certain times or learn to swim for free.


Swimming burns calories and can help you lose weight, as well as tone your muscles, improve general health and fitness.

By using many different muscle groups and the cardiovascular system, swimming can provide a great exercise for many people.

Scuba diving

Some common gases used for scuba tanks

Among us must have seen divers using air-breathing tanks underwater. Unlike other diving methods, relying on breath or breathing under pressure from the surface of the diver usually carries a breathing air source that allows them to move more freely than the hold breath.

So do you know what gas they carry with you?

Scuba diving tanks are metal tanks that are compressed with natural outdoor air inside, not oxygen. Used to provide gas for you to breathe in the water for a safe time. There are valves for opening and closing.

Scuba Cylinder Care — O2ToGo Dive Centre

There are many other types of tank capacity available, depending on the size and pressure resistance of the tank. The volume of the bottle is measured in liters or kilograms. By compressing the air, a small bottle can hold a very large amount of air. There are 3 common sizes: 8, 10, 12 liters. In some diving cases it is necessary to combine 2 tanks to get more diving gas for longer. The pressure of the gas diving tank can withstand higher than about Mpa (320 bar). Typical pressure is 20.7, 27.6 (207 – 276 bar).

Some common breathing gases:


A mixture of oxygen, nitrogen and helium gas and is often used in deep diving in engineering and commercial diving instead of air to reduce nitrogen toxicity and to avoid the risk of oxygen poisoning.


It is a mixture of Oxygen and helium gas and is often used in very deep diving to eliminate nitrogen poisoning.


A form of trimix that is blended from helium and air without mixing with pure oxygen. It always has a ratio of 21 oxygen and 79 nitrogen. The balance of the mixture is helium.


A mixture of oxygen, helium, and hydrogen and is used to dive below 130 meters.


A mixture of hydrogen and oxygen gas, used as a breathing gas for very deep diving.

Some common gases used for scuba tanks:


A mixture of 21% oxygen, 78% nitrogen, and about 1% other gases, mainly argon. To simplify these calculations the last 1% is usually treated as if it were nitrogen. It is the most popular diving gas. Due to its nitrogen content causes nitrogen toxicity. It was only used to dive up to 40 meters (130 feet) deep.

Pure oxygen:

Mainly used for acceleration of military, commercial or technical diving and is only safe to a depth of 6 meters (maximum operating depth). Through this depth, it is susceptible to oxygen poisoning.


A mixture of oxygen and air, and generally mixtures with more than 21% oxygen. It can be used as a tool to speed up decompression nodes in water or reduce the risk of decompression disease and thus prolong diving time.

Helium is present in most gas mixtures used in scuba tanks. Thereby, we can see the importance of helium how. In addition to gas for helium scuba diving, there are other uses and applications for other fields such as medicine, welding, cold electronics, …
