Why do you think a lumberjack's life is full of hardships?

A lumberjack leads an isolated life which is full of hardships.

1. They set out in autumn to live in temporary wooden houses, or shanties, with steep roofs. Sometimes, constructing a house becomes a problem due to permanent frost on the ground.
2. Therefore, in summer, the lumberjacks build many kilometres of rough track roads deep into the forest. This track leads to the lumber camps, which consist of a few buildings with a kitchen, a dining room and a bedroom.
3. The climate is extremely cold, especially in winter, making outdoor work very difficult.
4. They have to cut down large trees using heavy tools and machinery, which is physically exhausting.
5. In the past, lumberjacks returned home walking many kilometres after several months of stiff work in the forest.
