Physically demanding doesn't necessarily mean heavy. Moving at a rapid pace for extended periods is considered physically demanding. If you're in regular shape at 50 or 60, this is tiring but absolutely doable for a few days or weeks. I'd even argue that it's healthy to physically push yourself. But someone else noted that these temp workers aren't expected to hit the same output.
