Guess Who's Forty?

Yesterday was my 40th birthday.  Actually I welcomed it, and as predicted, 40 feels the same as the year before.  I did tell my students and my own children that now I'm officially "old."

So my goal was to run 4 marathons  before I turned 40.  I finished the 4th last fall.  Now I need a new exercise goal--because I don't find exercise convenient for me.  I rarely "crave" exercise.  I was looking out at the sleet (supposedly preceding a snow storm).  Maybe I could make my goal to complete 40 miles each month I'm 40.  The breakdown is ten miles a week.  That seems reasonable, right?  Perhaps since the weather is bad I can start . . . next month?
