user: What are the key elements of a sauna?

assistant: Saunas are a room with a heat source that will hold room temperature between 150 and 220 degrees Fahrenheit. The heat source is electric or wood fire. Typically saunas have an 8’ ceiling, and the size of the room is optimized for the number of people that are expected to use it concurrently. Saunas also need benches. The optimal bench depth is 24” to allow users to lay down comfortably. Bench and wall paneling is typically western red cedar, although other wood types that can withstand high swings in temperature are suitable as well. Proper wall, ceiling, and even floor insulation is critical, and given there will be water vapor in the room, there needs to be a vapor barrier between the wall panels and insulation. A floor drain is also highly encouraged.

user: Tell me about the inversion in postcolonial theory

assistant: The term derives from studies of modalities of resistance by the Subaltern Studies school, but reflects concerns pervasive from the earliest days of post- and anti-colonial writing. 

Ranajit Guha refers to inversion as one of the modalities of peasant revolt in colonial India, noting practices such as forcing landlords to carry peasants on Sedan chairs.
