I hate sudoku. Haven't figured it out yet.

I'm pretty good at freecell, though...

Keeping the mind working is a very good thing. I highly recommend it. I think it keeps people alive.

I'm fortunate. I have a job that keeps my mind working - sometimes 24 hours a day. I dream about shuttle launch trajectories (I'm strange...). We only have a window of 2 to 6 minutes to launch on a given day.

Next launch is March 11th, by the way...
