Not surprised, nearly all of my dad's friends have lung disorders. In fact, 2 of my uncles passed away because of lung cancer.


A big reason why lung cancer cases are soaring, is actually because of China's aging heating system. Every city in northern china has centralized heating in the apartment buildings.

Most of these furnaces are still fueled by coal! They cause a huge amount of pollution, and when some cities finally switched to natural gas, the air quality instantly shot up.
