Should Marriage Licenses Expire and Be Renewed Every Year?

Although the vows in many marriage vows end with ""as long as you both shall live," seldom do marriages live as long as the two people involved.  People change over time, and there has been a suggestion that perhaps the burdon of staying married "for life" is just too big of an expectation. What if your marriage license only lasted for one year at a time and had to be renewed yearly? If you had a chance to evaluate your marriage each year and decide if you wanted to renew the license, would it be easier to marry someone? Would couples try harder to stay together, knowing they would have to decide whether to renew the marriage at the end of the year? Perhaps, rather than divorce, couples could just wait patiently until the end of the year and simply choose not to renew the marriage license. Would this remove the expense and emotional trauma of divorce?
