What was the predicted cause of Vincent's death, and at what age was he expected to live?

Vincent's predicted cause of death was linked to a genetic predisposition to heart disease, which reflected the society's reliance on genetic profiling to determine an individual's life expectancy and health outcomes. In the context of the film "GATTACA," individuals like Vincent, who were conceived naturally and not genetically manipulated, faced severe discrimination because they were seen as inferior.

The age of 30.2 years was significant because it illustrated the deterministic view of genetics prevalent in that world. People were judged and limited by these predictions, which shaped their opportunities and societal roles. This creates a critical commentary on the implications of eugenics and genetic determinism, highlighting the tension between one's potential and the constraints imposed by genetic expectations.

The choice embodies the overarching themes of the narrative, making it a poignant point of character development and societal critique within the storyline.
