Ah fool, ah fool, it is not about dying, it is about health
issue. Non natural air (circulating air) have never been good to
health, but because of our weather and rich habitual, most of us
love to sleep in Aircon, including at Home.
But like it or not, it creates lots of health issue including
bones degeneration, rheumatoid arthritis, muscle deficiency and
reduction, skin dryness leading to many skin problem including
eczema, etc etc. And we tend to be more tire sleep in aircon than
with natural air.
