Why do people wear these things?
Don't these people know they make everyone else sick?
For those who wear perfume: Please do not spray it directly onto yourself. Spray one pump into the air in front of you and then walk through the mist. Never use more than that!
For those who wear hair spray: Please only use a product marked "unscented" and spray using short bursts. If you are holding the spray nozzle down and waving the can around, you are doing it wrong.
If you think that is not enough, begin to repeatedly slap yourself in the head until you no longer think that.
