What does the Revelation of Eels tell us?

There is an eel in the deep water area of Hokkaido, Japan, which has delicious meat and delicate nature. As long as you leave the deep water area, you usually die before you reach the shore. Only old fishermen can get eels ashore alive, so they can sell several times more than other fishermen in the market. The old fisherman didn't tell the secret to his son until he died. It turned out that he put the pike in the fish tank. Barracuda is the natural enemy of eel. As soon as he entered the cabin, he and the eel chased each other, and the fish cabin showed a scene of natural selection. In this way, eels are alive before landing.

After reading this story, people can't help but sigh. The result of competition is not necessarily a larger foe, but it has become a trick to bring back the dead. Unfortunately, the old man is just a fisherman, but he is familiar with the "secret" that many managers have been kept in the dark, and understands that only competition is the necessary condition for youthfulness.
