Pneuma.

This usage is the earliest extant occurrence of the term in philosophy.[4] A quotation from Anaximenes observes that "just as our soul (psyche), being air (aer), holds us together, so do breath (pneuma) and air (aer) encompass the whole world. " In this early usage, aer and pneuma are synonymous.[5] Ancient Greek medical theory[edit] The disciples of Hippocrates explained the maintenance of vital heat to be the function of the breath within the organism.

There's old insulation in the attic labeled "rock wool." Is it really dangerous asbestos?

It is a type of thermal insulation made from rocks and minerals, unrelated to asbestos. The material is also called mineral wool or slag wool, and some versions of it are actually a recycling of industrial furnace slag. The most common types of rock wool are categorized by the International Agency for Research on Cancer to be “not classifiable as carcinogenic to humans.” The material may, however, cause skin irritation, and it is always a good practice to wear gloves and other personal protective equipment while handling it.

Rock wool is produced naturally during volcanic eruptions, which is how the fiber was first discovered: in the early 1900s, Hawaiian volcanologists found unusual, wool-like clusters of fiber hanging from trees around Mount Kilauea. Today the volcanic process is replicated in industrial furnaces, where the minerals are heated to approximately 2900º F, then subjected to a blast of steam or air.
