Korean gas heaters and their dangers

The podcast discusses the use of mobile gas heaters in Korea and Mexico in the 90s. These heaters released gas and heated rooms through filaments. However, they also posed a danger as they caused fires and suffocation, especially in Mexico. It was discovered that even a little wind could disrupt the flame, leading to potential accidents. The speaker recounts how his companions in Korea would test their 'G' or 'Chi' by blowing air across the heater to make the flame ripple. This practice became a way to ask someone how they were doing.
