@lippyent There are three things we smell just before a thunderstorm. We can smell dust, carried by the wind that precedes the storm. We can smell the water content in the air (humidity), and we can smell the difference in the air, caused by the negative ions that the lightning produces.
@iqrafatma1278 You are overreacting! Men have always worked outside without their shirt. I think you should mind your own business, and leave others, who are doing nothing wrong, alone.
