Answer:
They used to live lonely lives and work a lot.
Step-by-step explanation:
In one way or another, the U.S. cowboy, Mexican vacquero, and the Argentine gaucho used to live in the same environment, but in a different context. All of them used to spend a lot of time outdoors, working in the fields or taking care of the cattle. Due to this, they also were used to loneliness for long periods of time. Another characteristic is hard work since they days started very early in the morning and finished before twilight. They were also very skilled with horses and knew how to deal with farm animals.
