Rabbi, you’re just wrong. Look it up. It;s even a Mchlokes in the Gemara whether or not a Traifeh can live for more than a year. These are Mishnayos in Chullin as to what is a Treifah and what is not. It is not at all dependent on length of life. Are you telling me that if I kill a Goseis I am Chayav Misah but if I kill a guy with twelve months to live because of a tiny hole in a lung I am Pattur? That’s how it works. It’s a Din that Horeig es Hatreifah is Pattur and it doesn’t matter how much time they have left to live. If the Treifah is curable but the hole he is still there he is definitely a Treifah. The Mishnayos don’t say that Treifos die, they say what constitutes a Treifah.
And milk with other milk is Lach. If I have 20 buckets of milk from 20 cows those are Yaveish compared to each other until they are mixed. Lach and Yaveish aren’t determined by states of matter, they are determined by how the Ta’aroves interacts with each other. That’s why flour is considered Lach because the Ta’aroves (of two batches of flour) is made up of combined, indistinguishable particles. So separate bottles of water that are indistinguishable but definitely not combined are considered Yaveish.
