Well obviously I’d like it if all my key parts were redundant and I could live for a thousand years. But my genome’s not interested in shelling out for anything like that; it’s cheaper just to replace me when I wear out. The only reason it even permits two eyes is so I can detect food and sex targets in 3D.
But the joke’s on you, DNA, because I’m resolutely gay and I refuse to do anything to advantage my genetic relatives.
