Synopsis by Hal Erickson
After Jackson (Michael Shanks) assists in the delivery of a baby on the planet Argos, the SG-1 team is invited by the planet's inhabitants to a joyous festival. The team cannot help but notice that the Argos population consists entirely of young, beautiful people who immediately fall asleep at sunset, awakening several years older the next day. It turns out that the Argosian lifespan is only 100 days, and that the inhabitants grow old at an accelerated rate. Seduced by the Argosian Kynthia (Bobbie Phillips), O'Neill (Richard Dean Anderson) inherits the planetary traits, ageing rapidly before his comrades' eyes. Carter must find out the cause behind this phenomenon--before O'Neill dies of old age.
