What is the predicted lifespan of Vincent, including the probable cause of his death?

The chosen answer highlights a critical aspect of the film "Gattaca," particularly in relation to Vincent's genetic predispositions and societal expectations concerning health and longevity.

In the narrative, Vincent is conceived naturally, which places him in the category of "in-valids" with a genetically inferior status compared to those who are genetically engineered for optimal health and capabilities. Due to this background, the medical community predicts that Vincent has a significantly shorter lifespan, estimated at 30.2 years, primarily linked to hereditary factors, with heart disease being identified as the probable cause of his death. This prediction reflects the film's exploration of genetic determinism, where individuals are often judged and pigeonholed based on their genomes rather than their actual abilities or character.

This focus on heart disease as the cause underscores the theme of inevitability that impacts genetically unaltered individuals, stressing society's reliance on genetic predictions rather than embracing a more nuanced view of potential and individuality. Vincent's struggle against these predetermined limitations is a central theme in "Gattaca," making this prediction both poignant and relevant within the context of the film's exploration of biotechnology and identity.
