I'm sitting here dripping with sweat after watering our garden. I can only imagine the horror of having to wear a gas mask in your scorching heat! Stay safe now, ok? We miss you.
I wore a gas mask for 4 hours last October. All I was doing was sitting on a couch watching TV (except for the first hour, when I tried to type out an e-mail, but got frustrated with the gloves). When done, I literally poured my sweat out of the mask. And it wasn't even hot, maybe 80 degrees and high humidity. Not 120-140 degrees.
