How Advertisers Convinced Americans They Smelled Bad 
Do you know what the bigger story is here?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.That salt kills-off the bacteria that are responsible for odor (through various means, directly and indirectly).After a week or two of this, you're done.  Your sweat lessens, and becomes clear and odorless.No more deodorant is required after this. Just shower and apply some soap to your skin.The bigger story here is that advertisers have convinced you that their more expensive "formulas" are required, and there are no good alternatives.Their products are specifically designed not to kill-off the bacteria, and hence to keep you purchasing the product.They do this because you can't make money selling a $1 peace of salt-rock that lasts the customer a life-time.
