my allergies are making my head hurt

and my email isn't helping.
Email #1:
This riddle must be done IN YOUR HEAD and NOT using paper and a pen. Try it!
Take 1000 and add 40 to it. Now add another 1000.
Now add 30. And another 1000.
Now add 20. Now add another 1000. Now add 10.
What is the total?
***
Did you get 5000? Way to go... most of us do, join the crowd!
But you know what? We're all wrong!
The correct answer is actually 4100. Don't believe it? Check it with a
calculator or on paper!
The brain sure knows how to play little tricks on us, doesn't it?

Argh! As if my head didn't hurt enough as it was.

Writers for the nation's top intellectual and
political magazines are almost always men. This is
made glaringly obvious by the ratios of male to female
writers below. (The figures are created by counting
male vs. female bylines from top magazines from Oct.
2003-May 2005. At several magazines, women writers
were occassionally shut out of entire issues):

National Review: 13/1
Foreign Affairs: 9/1
The New Republic: 8/1
Harper's: 7/1
The Weekly Standard: 7/1
The Atlantic: 6/1
The NY Review of Books: 6/1
The New Yorker: 4/1
The Nation: 3/1
Columbia Journalism Review: 2/1

The ratios were published in the current issue of the
Columbia Journalism Review.

If you were contemplating sending me an email that will give me a headache, might as well do it now.
