To Hat or Not to Hat

I exercised in the pool yesterday and wanted to try walking a little farther on land today, seeing how my joints and muscles continued to hold up.  Plus, the pool doesn't open until 11:00 and I needed to be done and back before my delivery window on a piece of furniture.  Didn't count on the humidity...

Pretty sure I was on the border of heat exhaustion and my 30 minutes stretched out to 45 because I had to slow down.  I've never been so grateful for patches of shade.  I remembered my hat this time, but I'm not sure the heat it contained was worth the tiny bit of shade it provided.  You wear a hat to stay warm, right? Maybe I need a visor?  With the sun coming in sideways at 9:30 am, it didn't even shade my whole face.  Suddenly going to the gym is sounding better and better.  That, and a nice cool shower.  Definitely pool tomorrow.
