What Deep Thinkers Men Are
I mowed the lawn today, and after doing so I sat down and had a cold beer. The day was really quite beautiful, and the drink facilitated some deep thinking on various topics.
Finally I thought about an age old question:
Is giving birth more painful than getting kicked in the nuts?
Women always maintain that giving birth is way more painful than a guy getting kicked in the nuts.
Well, after another beer, and some heavy deductive thinking, I have come up with the answer to that question.
Getting kicked in the nuts is more painful than having a baby; and here is the reason for my conclusion.
A year or so after giving birth, a woman will often say, "It might be nice to have another child."
On the other hand, you never hear a guy say, "You know, I think I would like another kick in the nuts."
I rest my case.
Time for another beer.

Oswald AveryBorn 21 Oct 1877; died 20 Feb 1955 at age 77. Oswald Theodore Avery was a Canadian-American biochemist and immunologist whose research on pneumococcus bacteria made him one of the founders of immunochemistry. His research laid the groundwork for modern genetics and molecular biology. Avery spent most of his research life at Rockefeller Institute where he made important contributions to the understanding of the pneumococcus organism, a particularly virulent bacterium that caused lobar pneumonia. Prior to Avery's work, genetic material was assumed to be protein. At age 67, Avery made his most important discovery when he proved conclusively that DNA from the nucleus of the cell is the genetic material, in a seminal 1944 paper co-authored by Colin MacLeod and Maclyn McCarty. |
MAGIC SQUARE: Calculate A*B*C
The aim is to place the some numbers from the list (6, 7, 9, 10, 15, 18, 19, 28, 31, 32, 38, 96) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A*B*C.
