Oh my! You made me feel a little bad now, mostly about the animals. I am a milk lover! And saying that by growing older it might not do us any good can't make me want it less though.

I'm sorry 🙁
But you shouldn't worry too much about the harms for your health, since you are an adult and can apparently digest milk - so you lactase gene work quite well, I guess.
Therefore, you only have to deal with the moral implications.

My point is, there can still be farms that treat animals with more decency.

I know. I'm not saying, that it's not possible - but very rare in comparison. Most of the dairy products are probably based on milk by said HF-cows.
