About the human body (health), use "husband" to express. There is basically no need to be "stubborn". When it comes to things, "stubborn" means "strong". "Tenacity" not only means that buildings or car lights or mechanical appliances are not easily damaged, but also refers to people's actual tenacious state by analogy. And "husband" means that a person is physically strong, and a certain part of his body is strong, which means that he is mentally strong and strong. When using inanimate objects such as objects, the meaning of "stubbornness" is simply changed.
I hope my answer can help you, remember to adopt it.
