Study shows shearing is toughest job in the world.

Guess they didn't compare it to hanging
live chickens at the beginning of the
chicken processing plant.
Bend down, pick up 6 in each hand and lift
them over your head and hang each one in a
shackle. Eight hours per day, 5-6 days per week.
Tyson Foods and Pilgrim are big chicken processors.
Every day they make about $100 usd.

Working in a sewer you would use protective clothing, as well as breathing apparatus.

Shearing a sheep requires a person to work in temperatures varying between -10*C to 60*C (inside some sheds). As well as dragging sheep weighing between 50-150kgs (ave 70-80kgs). Also working long distances away from home for months on end (as when Aussies/Kiwis come to Germany/UK to shear).

Just some examples.

I do everything you just described,

haha, Before I clicked i knew OP was either an Aussie or Kiwi.

Surely shearing is a tough job.

Toughest, most physically demanding job I ever worked
was unloading 50 kilo burlap sacks of coffee beans from semi-truck trailers.
I didn't bring gloves on the first day.
My knuckles were bleeding by 10AM.

Sorry if you got some of those blood stained beans.
