Unreasonable commitment to expect of people  The average age, in the UK, to get married is approximately 30 years old. (Office for National Statistics 1999) Life expectancy in the UK is approximately 80 years. (Office for National Statistics 1999) This means the average marriage expects people to commit to maintain a certain way of life for a period that is longer than they have actually been alive. This goes hand in hand with the rise of social acceptability of people having more than one life partner in their life to show that either marriage is an unreasonable expectation of someone or a meaningless charade that is not actually expected to be maintained.(Cherlin 2009)
