i think car exhaust is more dangerous than cigarette smoke.

nowadays everywhere you go you got exposed with car smoke. just dont have smell/odor only.

you also dont know what thing you inhale in car aircond.

our house roof also sometimes made of asbestos.

dont get started with our food today. god knows whats inside those processed items.

so many things can cause and trigger cancer. what is yayasan kanser is doing other than collecting donation?
