On orders of Pallas Athena, Queen of Olympus, Rhymer Enteprises is offering Earth either–not both–of two marvelous technologies. One is the ability to reverse the aging process; the other is the power to control the weather.
Choose the first, and RhE will make available technology based on the rejuvenation therapies described in Robert Heinlein’s Lazarus Long’s novels. These therapies are strictly scientific, not magical, in nature. They change a middle-aged or older adult to turn back the physiological clock to an earlier adult age, as far back as about 25. The physiological clock is turned back to the age you choose, and you can decide if your cosmetic appearance should match your internal one or not. In other words, if you think you were strongest and fastest at 27, but prefer the way you looked at 40 to the way you did at thaty age, you can mix and match. As a necessary side effect, the rejuvenation process cures any diseases you now suffer from, whether or not you had them at the physiological age you choose. The process is not instantaneous, and how long it takes to rejuvenate someone depends on how many years are being stripped away. Seventy-five years will take about two monthsof therapy. though not from the patient’s viewpont, as he or she will be conscious about three-quarters of the time.
The weather domination is based on STAR TREK: THE NEXT GENERATION technology. This satellite-based system allows the control of an M-type planet’s weather systems to a reasonably precise level. Want to send the California drought? The weather dominator will do it. Want to make sure Seattle only gets rain between midnight and dawn? We’re on that too. RhE will launch the satellites and keep them fueled for the next 250 years.
