The False dilemma in this instance is:

• to have health, you have to know disease
• otherwise you can’t have health

This is faulty thinking. Someone can be perfectly healthy while being completely ignorant of disease.

When I am cooking a meal, do I have to be aware that I need to be able to:

• smell the food
• taste the food
• use my hands to cook?

No, I just do these things without having to think of anosmia or possibly having my hands amputated.
