Oh man, I so want a margarita. Instead I am at home with a sick kid, trying to grade despite said sick kid's refusal to nap. Lame.
Also lame? My inability to understand the answer to the Monty Hall problem. Can someone explain it for the math-impaired?
there are three doors. when you do not know what is behind any of them, your chance of getting the prize is 1 out of 3. When a bad prize is revealed behind one door, there are STILL 3 doors, but now you know 1 of them, so your chance of selecting correctly now is bumped up to 2 out of 3.

Cognitive Ability Declines Starting at Age 27
Sorry to bring you the bad news, guys. Timothy Salthouse, Professor of Psychology at the University of Virginia studying cognitive aging, found that reasoning, speed of thought and spatial visualization start to decline at age 27:

Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60.
Professor Salthouse said his findings suggested "some aspects of age-related cognitive decline begin in healthy, educated adults when they are in their 20s and 30s."
So chose your victims carefully - brains are

Gender equality and political correctness aside, Mother Nature has decided the answer: female neurons are more valuable.
Writing in the Journal of Biological Chemistry, a group of researchers found that nutrient deprivation of neurons produced sex-dependent effects. Male neurons more readily withered up and died, while female neurons did their best to conserve energy and stay alive. [...]
