In Chicago it is always windy. I wear pheros before taking the train to the city. The train ride is 1 hour. Then walk for 10 minutes from train station to my office. It is very windy everyday.
My thoughts are that when I walk in the morning on the sidewalk I evaporate or lose all the pheros that I put on before jumping into the train. Do you think I am just wasting pheros this way? Shall I put them on after I reach the office?
