La vieja guardia

After having lived a relatively quiet life on Earth and on the same day they turn seventy-five, 1,022 elderly people join the Colonial Defense Forces, the army that fights for the survival of humanity in the universe. Life on Earth goes by without too many setbacks. However, a merciless war is being waged in the universe for the last uninhabited planets in the galaxy. The army that defends the cause of humanity is made up of elders. Elders who are given the body of a twenty-year-old. Without losing an iota of the knowledge and experiences of their previous life, their new bodies will make them rediscover sensations that old age had sunk into oblivion, they will once again feel the vigor of youth, attraction, desire and sex will regain meaning. However, the price they will pay for such a gift is high: they will travel to a remote and inhospitable place where the only important thing will be to fight and try to survive. And they will never be given the chance to return to Earth.
