in an ice age you're gonna create a certain mentality, so what is very natural becomes unnatural in the ice
a human being is only as great or as worse as his/her environment
in an ice age, when you are dealing with these temperatures, your babies are freezing in your arms to death, there is no mercy
when you're in the ice, you're not really thinking about healthy relationships, and quite frankly when the urge hits you, any hole will do
