True, some choose this way of life but not all do. There are no guarantees that life will go your way. Many people live pay check to pay check and it only takes one set back or hiccup to put you over that line. There are many sad stories that life has handed to some of these people: Layoffs, divorce, death, evictions, mental illness, health problems, and bankruptcy are some examples but the list goes on. 
Fall Kabib, it sounds like you have life beat. No worries about you or your loved ones becoming "very cold" because life is obviously going your way and their way and I truly hope it continues. I, myself, have been fortunate with a twenty seven year career in the oil industry and still going strong. However, I still worry about family, friends, and fellow Alaskans straddling that fine line.
