Ok, so why couldn't my professors at school have explained pathfinding in such a simple and succinct manner as this webpage? Pathfinding is an important computer science problem encountered over and over in everything from games to package routing to launching rockets at the moon. I never really had that aha moment before when discussing, reading about, or implementing pathfinding code.

Oh well - it didn't work. Being in a confined space like a house with someone sick inevitably leads to more people getting sick .... like me and Luann. We've both got what he had. He was out for 3 days. I'm now on day #3 and it's finally starting to let up just a bit. At least i can breath this morning and the coughing has stopped.

What to do ... It seems like over the years the human population has built up quite a catalog of viruses that transmit from person to person in never ending waves. It would be cool to see an animation of the flu and cold virus's as they spread around the globe in a constantly shifting pattern, going from here to there, changing intensity, mutating, infecting everyone in sight.

If only it were possible to take every single person on the earth, physically separate them from each other for a week or two (long enough for any viruses to have run their course and been attacked and killed by the immune systems). Then when everyone got back together, nobody would be sick. We could get on with our lives without having to worry about the common cold and flu viruses being all around us!
