I'm outside working on a storage shed that I'm building. Temp is 100 degrees with 45% humidity (thats low humidity for here, folks). I work about 20 - 30 minutes, then come in for about 20 minutes and drink lots and lots of water. Honestly, we usually don't get to 100 that often here near the coast. Tomorrow is supposed to be 103 - hottest its ever been in the eight years I've lived here, and I'll be roofing the shed - with black shingles! Oh, Joy!
To think, 20 years ago this month I was in basic training at Ft. Bliss, El Paso, wearing dark green battle dress uniforms in the 115 degree heat (at least it was a dry heat). Amazing how an extra 20 years can change how well you tolerate the heat!
