Still, though, I'm curious as to the *type* of bacteria the student found. Our hands and mouths are bacteria-ridden, but they're usually bacteria that our bodies deal with daily. I wonder how much and what types of bacteria we'd find if we tested a freshly made sandwhich (whole wheat bread, of course).

As far as bottled water goes, I'd like to see that tested too (again, for bacteria TYPE) and thought of mentioning it the first time around.

Is there not bacteria in our bloodstream? And.......is all bacteria bad for our health? (I really don;t know the answer to these)
