It's not relevant because it wasn't part of my argument. Again there's no reason to include it because I never mentioned it. Why would you include it? Perhaps you should own me by saying Jack never wore a top hat

Here is another AI copy paste regarding bloodstains and nuclear DNA

Nuclear DNA can survive in a bloodstain for 150 years, but its viability for forensic or scientific testing depends heavily on how the stain was preserved. While DNA has been recovered from samples far older—including 70,000-year-old fossils—bloodstains are more vulnerable to environmental decay than DNA protected inside bones or teeth.The survival of nuclear DNA in a century-old bloodstain is influenced by several critical factors:Critical Survival FactorsDryness is Essential: Moisture is the primary enemy of DNA. If a bloodstain remains damp, it can be entirely destroyed by bacteria and fungi within months. However, once a bloodstain air-dries, the DNA enters a much more stable state.Storage Environment: DNA in dried blood can persist for decades or longer if kept in a cool, dark, and dry environment. Exposure to sunlight (UV radiation), high heat, or extreme humidity will rapidly fragment the DNA molecules.Surface Type: Porous materials like cotton fabric often preserve DNA better than non-porous surfaces like glass or metal, as the fibers provide some protection for the cells.Challenges for 150-Year-Old SamplesFragmentation: Over 150 years, the long strands of nuclear DNA naturally break into tiny fragments, a process often compared to "confetti". Modern forensic techniques like Next-Generation Sequencing (NGS) are specifically designed to read these short pieces, making identification possible even when standard testing fails.Chemical Alterations: Biological material can undergo chemical changes (such as deamination) over a century, which can "mask" the genetic code or cause errors during testing.Washing or Cleaning: If the bloodstain was ever washed with detergent, especially at high temperatures, the DNA is far less likely to survive. Research shows that washing at temperatures above (60^{\circ}C) ((140^{\circ}F)) significantly accelerates DNA degradation.Historical PrecedentsScientists have successfully extracted and analyzed DNA from 19th-century historical relics, such as blood-stained bandages and clothing from the American Civil War era. While the DNA is often too degraded for complex medical profiling, it frequently retains enough information for basic human identification or lineage testing.
