How Advertisers Convinced Americans They Smelled Bad 
Do you know what the bigger story is here?<p>You can purchase a mineral salt-rock crystal (it's a smooth solid peace of salt, about as cheap as it gets) "de-odorant" that you wet and apply, it leaves nothing behind except an undetectable amount of salt on the skin. That is ... no chemicals, no fragrances, nothing but salt.<p>That salt kills-off the bacteria that are responsible for odor (through various means, directly and indirectly).<p>After a week or two of this, you're done.  Your sweat lessens, and becomes clear and odorless.<p>No more deodorant is required after this. Just shower and apply some soap to your skin.<p>The bigger story here is that advertisers have convinced you that their more expensive "formulas" are required, and there are no good alternatives.<p>Their products are specifically designed not to kill-off the bacteria, and hence to keep you purchasing the product.<p>They do this because you can't make money selling a $1 peace of salt-rock that lasts the customer a life-time.
