Hypothermia is one of the biggest risks to your life at high altitude. Hypothermia is defined as a core temperature below 35 degrees. It is broadly categorised into: Mild hypothermia (32-35 degrees C) Moderate hypothermia (30-32 degrees C) Severe hypothermia (<30 degrees C)
Churn rate. Churn rate (sometimes called attrition rate), in its broadest sense, is a measure of the number of individuals or items moving out of a collective group over a specific period. It is one of two primary factors that determine the steady-state level of customers a business will support.
Note that if the Customer Churn rate is a monthly % or yearly %, then the Customer Lifetime will be for the same time period. Here is a monthly and annual example to illustrate the point: a) If the Monthly customer churn rate is 3%, then the Customer Lifetime will be 1/0.03 which is 33 months. b) if the Annual customer churn rate is 20%, then the Customer Lifetime will be 1/0.20 which is 5 years.
