I had a question in a homework sheet:
Over two million bacteria are found per square centimetre of skin under armpits. Why Don't they cause disease more often ?
I guess the question is basically asking me, considering that there is so much bacteria under armpits, why don't armpits get infected with disease often?
I thought of some answers :
Sweat - some type of chemical that sweat contained that killed bacteria ?
Expose - Your armpits are exposed much so maybe the bacteria don't get enough of something
Help is appreciated
