This write-up is not talking about physical characteristics. It’s talking about strength of mind, character, perseverance.
There’s a rather famous phrase: To be strong is not a given, but to be weak is not a disease!
And here we are talking just about a person’s position in life.
A weak person simply can afford to be weak, and a strong person can’t. After all, if we look closer, there is always someone stronger, a decision-maker, next to the weak. He is responsible not only for himself, but also “for that guy.” In essence, he allows the weak person to be weak.
So there are no weak people in nature?
There are people who are comfortable being weak.
