<Sure, 30degrees and 90+ humidity is survivable, but only just.>
And how could you get any work done? I worked in the oilfields when I was in my early twenty's, if the temp was over 100F, less work got done because we didn't want to die. I knew men who got heat stroke, they were never the same again. I myself got heat exhaustion several times, it took a few days to recover. Our bodies can only take so much, no matter how tough you are, wet rags and frequent breaks don't always work.
