prolong

v. extend, lengthen, make longer

In the fictional Honor Harrington universe, prolong is a genetic engineering process for life extension. It was developed on Beowulf two or three generations prior to the series' present (the early 41st century), but is prevalent or at least present in almost all advanced star nations. As of the events of the Honor Harrington series, prolong has only been recently introduced in less developed areas, such as pre-alliance Grayson and the Talbott Cluster.
