I don't need to be mentally stimulated, but to know that I do something worth doing is my focus. Conditions are not to be downplayed though. Seriously, they wanted you to do such a physical job w/o A/C? ridiculous.It was constantly over 100 degrees in there and they would no turn on the A\C they had because it would cost money. I had to walk around 10-14 miles a day working 5 days, 10 hours per day with a bit of mandatory overtime thrown in occasionally.
