I have to give that to you, I've worked at jobs that were hard work. I humped wheelbarrows full of concrete for 12 hours a day on one job, (building Grain Elevators) working from 7PM til 7AM got to see the sunset and the sunrise. I've lumberjacked, commercial fished, lots of construction oriented work. I had a sign painting business and I've done sign installations for a sign making company. I had a Kitchen and Bath Remodeling business. I worked in the hotel industry for 20 years or so, first as a maintenance man and then as a Chief Engineer, Director of Maintenance & Engineering where I did budgeting and scheduling of all the work for the facilities that I worked at, but I would always walk the entire property every day and check in on my employees to see that they were doing their jobs and if they needed anything.
When I was remodeling it was nothing for me to carry a couple hundred pounds at a time, I didn't even think about how heavy anything was until I would see someone struggling to pick up something that I just set down. My son (soon to be 27) and I would carry, not bounce a 400# plus cast iron tub up stairs in clients houses, so as not to damage the stairs, and I would be at the bottom because I didn't want my son getting hurt.
