Two-Four Tuesday (v.3)

Last week's "Top Five" list of the names given to male cats generated 2 comments and an e-mail. Thank you, visitors! Seems like the guess for #2 was easier (Tiger) than the guess for #4 -- Shadow. Thank you, Veterinary Pet Insurance, for posting the most popular pet names on your website.

Did you know that (according to Petfinder) while dog households outnumber cat households, there are more cats (64.1 million) than dogs (63.8 million) in America?

And now, on to today's game. We hope you'll play along again!

I will post the "Top Five" items in a list, except that I'm leaving out the 2nd and the 4th items. Your mission -- comment with your guesses (or "answers", if you're that confident) as to what the missing items are. Don't cheat by looking up the info on the web -- just have fun and take your own guess. I'll give the correct answers the following Tuesday.

Top Five leading causes of disability adjusted life years (DALYs) in the world, among 15-44 year olds, according to the Global Burden of Disease study by Harvard University.

1. Unipolar major depression (43 million DALYs)
2. ??
3. Road traffic accidents (19.6 million DALYs)
4. ????
5. Self-inflicted injuries (14.6 million DALYs)

(Your hint: one answer is an infectious disease, and the other is a behaviorial disease. Neither are bipolar disorder -- that's #6 on the list.)
