I totally agree that the first human to drink animal milk was probably a very weird person. Although it probably came out of a goal to not waste resources.
There's not really a "reason" that people become lactose intolerant around age 2. Especially when most people are weaned off human milk way before then. Also, to say that there is a reason implies that humans were designed by some omnipotent force. There's plenty of times in a human's life where the nutrients found in milk would be beneficial to have, like after a woman goes through menopause.
It is only recently that we have an abundance of resources that we can choose where we get our nutrients from. And if one were really living off the land, they would not have that choice.
If I had animals that were already lactating, I'd probably make cheese. I would also probably make 2 different batches to do a side by side test between pasteurized cheese and non-pasteurized cheese just so I can see if Europeans are right.
You mean double walled vacuum insulated? Yeah, they make titanium wide mouth bottles like that. I bought one like that made from titanium with almost no lip for about $50 recently. It's so easy to clean.
I like wide mouth bottles that match the diameter of the rest of the bottle, because they are the easiest to clean. You can even just toss them in the dishwasher depending in the material.
I also try to only buy titanium bottles since they last a lot longer than stainless steel. Some brands are too expensive but ive gotten lucky in the past with no name brands.
Agreed, although I could see an argument for roosters. However, I love mine.
