I cannot breathe any kind of candles/air fresheners/fabric softeners/perfumes anymore. Actually it is better for your health not to have these things around, as they contain lots of chemicals.
Actually what i think if we maintain equilibrium with inner and outer atmosphere of body we will never face any problem untill we are over age.But tremendous industrial development unable us to do that and what my analysis tells is that the frequency of diseases is directly propotional to frequency of chemicals we are decovering.I dont say we should not make new new decoveries but not to impliment them in excess.
