Alot of people can't smell their own BO, so alot of times they don't knpw they're stinky unless someone (nicely) tells them.
true....but if you shower...every day....and/or agfter working out or doing yard work or something else that makes you sweaty, this shouldnt be an issue. if you do all of the above, and you still stink, invest in some stronger soap. Or see a doctor.
I had a co-worker at one hospital who used crystals for all kinds of things. She claimed to have a crystal that you could wave under your arms and it worked like deodorant. She frequently bragged about it. Thing was, it didn't work and she ALWAYS reeked of BO. It was so gross!
