Personal opinion: There are probably two kinds of health challenges: 1. Objective factor 2. Subjective factors!
Objective factors mainly include: environmental factors, healthy diet, work factors and so on.
Subjective factors mainly include: family factors, physical factors and psychological factors, among which psychological factors are the most important!
For example, if a person has a good family, good grades or good work, but poor psychological endurance, then she will gradually get sick (the so-called illness is not only physical pain, but psychological illness will often lead to this disease slowly).
