Rollback

An elderly scientist, Sarah, is needed to work on communicating with messages from another star. So, what happens when this important woman is offered the chance to "rollback", become younger, so she can continue her work? She insists that her husband is given the opportunity also. Unfortunately, the situation is that it works for the husband, but not for the wife. It's an entertaining, sometimes poignant, story dealing with emotional and philosophical issues caused by human longevity.
