Application of comparative advantage.
The principle of comparative advantage explains the benefits of interdependence and **. Because interdependence is so prevalent in the modern world, the principle of comparative advantage has many applications. Here are two examples, one with novelty and the other with extremely important practical importance.
Tiger? Should Woods mow the lawn himself.
Tiger? Tiger Woods spends a lot of time walking around the grass. He is one of the most talented golfers of his generation, and he can hit the ball and get it inside the hole on the path that most non-professional golfers can only dream of.
In all likelihood, he excelled in other activities as well. For example, we can imagine that Woods could mow his own lawn faster than anyone else. But just because he can mow the lawn quickly, does that mean he should?
For this question, we can use the concepts of opportunity cost and comparative advantage. For example, Woods can mow the lawn in 2 hours. In those same two hours, he was able to make a TV commercial for Nike shoes and earn $10,000.
Compared to him, who lives in Forrester next door to him? Gumpu was able to mow the lawn of the Woods house in four hours. In these same 4 hours, he can work at a McDonald's shop and earn 2 0 dollars.
In this example, the opportunity cost of woods mowing the lawn is $10,000, while the opportunity cost of Forrester is $2 0. Woods has an absolute advantage in mowing the lawn because he can do it in less time. But Forrester has a comparative advantage in mowing the lawn because of his low opportunity cost.
In this example, the benefits are enormous. Instead of mowing the lawn, Woods should have gone for a commercial, and he should have hired Forrester to mow the lawn. As long as he paid Forrester more than $20 and less than $10,000, both sides would be in a better position.

Questions and answers for conscription physical examinations.
The fifth round is coming!
If you have a scar, you can't be a soldier?
Falling, touching, scratching.
Even left behind by mosquito bites.
These scars. Are they all without exception?
Today for everyone.
Interpret it carefully. Physical Examination Criteria.
Article 10 of the Physical Examination Standards for Recruited Citizens: Scar constitution, scars with a length and diameter of more than 3cm on the face and neck or scars that affect function, and scars that affect function in other parts are not qualified.
Unscramble. There are three types of cases.
The first case, which is more special, is that people with scar constitution are not qualified. For people with scar constitution, once there is an injury on the body, the surface scar will appear pimple-like after the wound heals, and it will continue to increase, and there will be local pain, redness and itching, and the scar shrinkage will also affect functional movement.
PS: How do you know if you have a scar constitution?
If you have been injured before, the wound will be higher than the other ** around you after healing, it will be very hard to the touch, even itchy, and the scar area is larger than the original wound, then you are likely to have a scar constitution.
In the second case, there is a scar on the face and neck, and the scar is on the face and neck and the length and diameter are more than 3 cm, which is not qualified; Scars that do not exceed 3 cm in length and diameter on the face and neck, but affect function, are also not qualified.
In the third case, scarring on other parts of the body, regardless of size, is not qualified as long as it affects function; If it does not affect the function, it is qualified.
As for the question of whether it affects the function, it is still necessary for the doctor to make a conclusion on the spot, and it cannot be judged by one's own feelings alone, after all, it is necessary to comprehensively consider the particularity of the soldier's mission, and the changes that may occur in the body in complex environments such as high altitude, deep sea, high pressure, strong light, confinement, plateau, and high cold.
Some friends will ask, I have had surgery, left a scar, not in the face and neck, and now it is better, am I qualified? Regarding this question, I would like to say that what kind of surgery you have is the focus of the doctor's physical examination compared to the scar. It is important to know that the impact of surgery on physical health is far more complex and subtle than external scarring.

Condition analysis: It depends on what branch of the military you are, and pilots are not allowed to have it. Because the acceleration of a fighter jet may cause the acceleration of blood to break through the scar, it is strictly limited.
The general military does not exceed two centimeters, and it does not affect the appearance of the military (such as on the face). Yours on the neck, it depends on how long it is. No more than two centimeters should not matter.
