Sometimes you just don't know that you're smelling really bad... Carry this device and you will know when its time to either take a shower or spray that heavy 24hrs deodorant! This device will measure the amount of sweat in certain places, combined with the time it's statying there, and the indicator signales you! Ideal when having a cold!-- BartJan, May 29 2001 like this? http://www.halfbake...oom_20smell-o-meteri guess it would work on the same principles.
