Gee...I'm a scientist by schooling (B.S. Biochemistry, some graduate course work...), and I don't know precisely what percentage of the earth is covered in water (I think it is about 75%, is that close enough for Dr. Amy???) nor do I have the foggiest clue how far away the moon is.

But does not knowing these things have ANY impact on my day to day life?  Not in the least.  What does have an impact on my day to day life (because I'm an Environmental, Health, and Safety Specialist) is EPA and OSHA regulations...which I'm quite well versed in, and I'd bet in a pop quiz on those topics I'd beat Dr. Amy quite soundly.  And really, the principles behind these regulations have MUCH more of an inpact on working Americans than knowing how far away the earth is from the moon or how much water is on earth.  Because...uuummm...oh, wait...I guess I'm not helping Dr. Amy out with my job because...

...the primary function of my job is to KEEP PEOPLE OUT OF THE HOSPITAL.

LOL.
