(at around 11 minutes) Braun says that the name, "Hindu Kush", translates to "killer of Hindus" and was given by locals because they believe that the gods made the weather for the purpose of killing men. Translation is correct, but not the explanation. It was actually named so because it was the route that Iranian slave traders used to transport Hindu slaves, captured in India, to Turkmenistan for sale. Many slaves died from exposure because their captors did little to protect them from the cold. Normally, only the foreign slaves died, who were mostly Hindu.
