If, like me, you distrust the aluminum in mainstream deodorants, I want to mention a natural alternatives= that survived long walks in the Alabama summer, let alone lesser trials:
Nutribiotic Deodorant Stick With GSE. It's also fragrance-free.
NB: if you know hard-working, responsible young people looking for jobs in this Bushbama recession, Amazon is hiring 50,000 seasonal workers. The pay is good and the work is important, and good employees will be offered full-time jobs.
