I disagree on mass sentencing reduction with Senate Judiciary Committee Chairman Chuck Grassley.  In other areas, however  --  most notably, at present, insuring that the electorate has a say in replacing Justice Scalia  --  I admire his work.  My admiration took an uptick when I read this article in Roll Call:

Sen. Charles E. Grassley, R-Iowa, is turning 83 on Saturday and he celebrated in his favorite way: by running six miles.

The senator traditionally runs from his townhouse in Arlington, Va., to the Capitol on his birthday, The Des Moines Register reported in 2014. On Thursday morning, he posted a photo on Instagram of his running watch showing that he ran 6.23 miles in an hour and 31 minutes. That's a little bit under 15 minutes a mile. At almost 83 years old.
