If we all knew each morning that there was going to be another morning, and on and on and on, we's tend not to notice the sunrise, or hear the birds, or the waves rolling into the shore. We'd tend not to treasure our time with the people we love. Simply the awareness that our mortal lives had a beginning and will have an end enhances the quality of our living. Perhaps it's even more intense when we know that the termination of the body is near, but it shouldn't be.
