I have been using deodorant for the majority of my life. Since I was in junior high school I have used Old Spice, a variety of different scents. In fact, until recently, I have always used the Pure Sport. Here is something I have noticed since switching from Pure Sport, to the new exotic scents like Denali, Fiji, or Belize: they do not last nearly as long.
Seriously, a stick of Pure Sport would last me around four months, whereas this new stuff lasts about two months. I wonder if Old Spice purposely changed the formula around so people would have to buy deodorant more often? It is not like I have suddenly decided to start wearing more deodorant. I take the same number of showers per day.
Anyways, that is my stray observation of the day. Go about your business.
