When we were growing up our parents ensured they subjected us to hard conditions, apparently as a way of preparing us for an uncertain future. Their survival and that of those before them had largely been influenced by their ability to withstand tough living conditions.
The ability to suffer silently was an applaudable trait that each mother instilled in their daughters before marriage. Perhaps Darwin intended this when he said "survival for the fittest". You must find a method to survive through those trying times, even if it involves eating your family members.
