The video discusses several topics, including the commercial practice of ruminot or mia, the use of fistula cows, the purpose of a fidget spinner, the function of tears, the use of a weather vane, and the ethical concerns related to animal treatment.
1. Ruminot or mia is a commercial practice where the back of cows is pierced to leave a hole large enough to fit a human arm. This practice is controversial as it involves leaving cows with their stomachs open throughout their lives. The main purpose of this practice is commercial, but animal rights organizations like PETA have criticized it for causing unnecessary suffering to the animals.
2. The video also discusses the use of fistula cows, which are cows that have had a piece of their abdomen removed to explore their stomachs. This practice is used to study the digestibility of the food and look for the most economical and efficient food so that the cows can assimilate better and produce more milk and protein.
3. The fidget spinner, a popular toy, was originally created to reduce stress, relax, and improve the ability to concentrate in people with attention deficit disorder. The video also explains the function of tears, stating that they help keep the eyes hydrated and protect them against infections. Tears also have a close link with our emotional state and can act as a natural pain reliever.
4. The video also explains the function of a weather vane, a rotating device that indicates the direction of the wind. This device is used to obtain an accurate reading of the direction of the wind, allowing users to predict future changes in weather.
5. The video ends with a call to action, urging viewers to consider the ethical implications of the practices discussed and to take action if they believe these practices are causing unnecessary suffering to animals.

The\n00:00:18.03: saddest thing is that these animals remain\n00:00:20.01: with their stomachs open throughout their\n00:00:23.04: lives in this video you will see five things that\n00:00:25.95: you did not know what they are for part number 7\n00:00:29.36: number 5 without a doubt cats, along with\n00:00:33.27: dogs, are one of the pets\n00:00:34.95: preferred by man, considered\n00:00:37.23: sacred by some cultures, the\n00:00:39.57: cat is the protagonist of multiple\n00:00:41.70: legends and myths, the best known They are\n00:00:44.40: that they have seven lives and their incredible\n00:00:46.74: ability to always land on their feet, but\n00:00:49.86: another of the unknowns that we all\n00:00:52.02: ask ourselves is why cats have\n00:00:54.42: rough tongues and what they are for, and the fact is\n00:00:57.72: that the tongues of these animals are\n00:00:59.70: coated with a substance called\n00:01:02.12: keratin, the same substance that\n00:01:05.01: our nails are made of,\n00:01:06.93: and the ridges of the tongue help\n00:01:09.90: the animal drink water or any\n00:01:12.00: liquid. For example, when dogs\n00:01:14.61: drink water, they use their tongue as a\n00:01:17.28: kind of spoon, while\n00:01:19.35: cats only immerse their tongue in water.\n00:01:22.02: water or milk and the ridges\n00:01:24.30: are responsible for trapping the liquid\n00:01:27.27: that will later be ingested.
