To the Editor of the "Nowra-Cutva' Dany News"
Sm—As a resident of a part of the French Concession where luckily there are only few mosquitoes in summer, I never found it necessary to use a net at night, but just lighted one of those coiled incense sticks which are sold in the local stores.
To my surprise I was told that this is a very unhealthy habit and does affect the lungs after some time. As a matter of fact I noticed a very tired and drowsy feeling in the morning even after a long night's rest with plenty of sleep. Could this have anything to do with the incense fumes?
I wonder if any of your readers would be kind enough to give me some competent information on this matter.
