How often have you said to yourself, "I wonder what happened to Jane X"? (Substitute any person's name you wish.)
Personally, I've noticed a positive correlation between my age and the frequency of occurrence of this event, but we all know that correlation doesn't imply causality.
Every now and then, over the years, I've wondered what happened to Shirley Almon, of the "Almon Distributed Lag Model" fame. Of course I should have gone to the internet for assistance, but somehow, I never did this - until the other day.......
