When I was in high school, I came to the depressing realization that my body was immune to deodorant.  I would put it on in the morning after I took a shower, but by the middle of the day, I stunk like dog.  I figured it was my lot in life, so I'd better just accept it and walk around with my arms pressed tightly to my sides. 

But then in college, I received one of those Freshman Survival Kits which had deodorant among other stupidly nonessential essentials.  I quickly noticed that this deodorant actually worked, so it became part of my daily routine.  Oddly enough, this is around the time people started talking to me and becoming my friends.  I'm not sure if there's any correlation between armpit stink and friends. 

After a few months, the effect of the new deodorant wore off.  To test a theory, I went to the store and bought a completely new kind that I had never tried before.  And it worked great.  That's how I reached my conclusion:  The human body (or at least my human body) develops an immunity to a specific deodorant after a certain period of regular use.  And once this immunity is developed, it can't be overcome.  In high school, I used regular old Speed Stick (the green kind).  It smelled good before it touched my skin, but as soon as it was on me, it smelled weird.  And then after about 3 or 4 hours, it went from weird to bad.  And this is still true.  I've tried this "flavor" again recently and had the same results.  I also tried the kind from the Freshman Survival Kit again, and it had the same non-effect. 

However, there's a way around this:  Always rotate between 2 or 3 different kinds of deodorant.  For whatever reason, this seems to trick the body into not developing an immunity. #health
