Overdid it a bit

I felt so good when I got up this morning that I went on a walk.  Before today I have only been able to manage about one lap around the park and then I need to sit down.  I was feeling really great so I walked four laps.  Even after the laps I felt great and ate some delicious leftover turkey meatloaf Hillary made.  After that I went to Costco to pick up my pictures (problems with that) so I was at Costco for about 45 minutes and knew it was bad.  I think had I just walked and then took it easy I would have been fine but the Costco trip threw me over the edge.  I had to take some ibuprofen and sit on the couch the rest of the day.  It is a hard life!
