Please don't smoke! Because smoking is injurious...To health of those around you. Got puzzled! Yes, I also got puzzled when I saw the following poster Ad on the wall of one of the nearby tea stall that I visited today.
Please don't smoke. Smoking is injurious to our health!
The above is a dual meaning statement. Either, this is a general statement that says that smoking is injurious to our health. Or, this could also mean that if you don't care about your health, that doesn't mean our health is not affected when you are smoking around. After all, there is something called passive smoking.
So, if you really don't bother and care about your health, do care about other's health. Smoke in a lonely place. Don't smoke in crowd.
