The third of my four daughters was being questioned about her training before the last Olympics, and answered; My mother was the first American to win the world championships, so I called her for advice, and believe me, Mom is always brimming with advice, whether you want it or not … In fact,…
In my analysis of data on the oldest old from the Kaiser Permanente study, I started with cigar smoking because I have a friend who turned 65 last month. His annual physical went like this: Doctor: Do you still smoke cigars? Jim: Yep. Doctor: Do you still drink 8 or 9 beers every night? Jim: Yep….
(Yes, that title does sound like a lot of the spam comments I get. ) Last year, at the Gov. 2.0 conference in Santa Monica, Jean Holm, from NASA spoke about some of the opportunities for open data. I left with mixed feelings. On the one hand, the best examples she gave were, I thought,…

It’s that time of year, near the end of the semester, when I ask students to write down any questions they may have about material covered in the course.
