huspa1-10, Exercise 3: The three lenses across the course

Model answer:

Health: the nineteenth-century water cure (Chapter 3) and the prescription tradition and research on balneotherapy (Chapter 8), with warm water easing pain and stiffness, and the minerals' role less clear.
Habit: the regulars at Lukács and the smaller baths, early mornings and winter bathing (Chapter 6).
Social life: the chess players and party baths (Chapters 4 and 9), and the hotel guest at the Gellért (Chapter 5).

The same bath often serves all three at once, and different people notice different ones. Any reasoned examples are acceptable.
