What is Fear again? It is a sensation that our sensors have picked up from surrounding environment. Therefore, it is always there. It is a part of living entities.

We could creating a "safer" environment, usually by eliminating as many risk factors as possible. We see this everywhere recently especially for kids. And by product, we claim many things "dangerous." Otherwise, you cannot sell a "safer" environment.

We could isolate ourselves in some restricted, safe environment. Kind of, if you do not go out, you have no risk of getting hit by a car or invisible virus. Well at least it is an assumption. We have no idea the risk of being isolated.

We can train ourselves to detect and handle dangerous signal effectively. Instead of reacting to it, we can respond to it. It is the strategy that human has been practicing since the day one. It seems we have favored the other two more recently.

It is the best strategy proven by evolution.
