Unless you are an athelete or body builder, i don't see the reason to shave the armpit. But its all personla choice. The key is to be clean, healthy and not offend anyone with your smell. Taking showers daily and using deodorant should be enough to keep off body odor, however, every deodorant are differnet, so feel free to dry different brand if you feel the one you are using is not working for you. IF YOU CAN SMELL YOURSELF, TURST ME, OTHERS CAN. As far as oral hygene goes, spend some $$$ in a good Sonic Care. Believe me, you won't believe how nice and good that is. Second step is to use tongue scraper and use dental floss DAILY. Dental floss have also proven to lower you risk of heart disease. Once again, i strongly recommend you guys to invest in Sonic Care electric toothbrush.
