Imagine turning 75 and instead of facing the twilight years, you're offered a second chance at youth - with one catch: you can never return home again. This is the reality John Perry faces on his 75th birthday after visiting his wife's grave. Like many elderly Earth citizens, he's heard whispers about the Colonial Defense Forces' tantalizing offer: renewed youth in exchange for military service protecting humanity's interstellar colonies. The CDF specifically recruits the elderly, valuing their accumulated wisdom and life experience over youthful vigor. Their monopoly on "skip drive" technology enables faster-than-light travel and allows them to dictate terms to Earth while keeping their most advanced capabilities secret. For Perry and his fellow recruits (who dub themselves the "Old Farts"), the journey begins at Nairobi's space elevator, a towering marvel stretching from Earth to orbit - their first step toward an unimaginable transformation. "We're not making you young again. We're making you again, but better." These words from Dr. Russell reveal the shocking truth about the CDF's rejuvenation process. Instead of merely reversing aging, recruits undergo consciousness transfer into entirely new, genetically engineered bodies. These enhanced forms feature bright green chlorophyll-infused skin for supplementary energy, superhuman strength, heightened senses, and integrated "BrainPal" computers that interface directly with thoughts. In a deeply personal moment, Perry transfers his wedding ring from his original body to his new one - a symbolic bridge between his past life and uncertain future.
