A possible concise summary is:
The video discusses two common myths about the human body: that swallowing gum will make it stay in the stomach for seven years, and that sleeping on the left side of the body has health benefits. The video explains that the first myth is false, as gum will pass through the digestive tract in two to three days, unless swallowed in large amounts. The video also explains that the second myth is partially true, as sleeping on the left side can help with acid reflux and circulation during pregnancy, but not in general. The video ends with thanking the viewers and promoting their products.
Here are some key facts extracted from the text:
1. The text is about truths and lies about the human body, focusing on two topics: swallowing chewing gum and sleeping on the left side.
2. Chewing gum is made of sugars, flavoring, artificial sweeteners, dyes and gum base, which is a mixture of elastomers, waxes, resins and fillers.
3. Chewing gum does not get digested or broken down by the saliva, stomach acid or pancreatic enzymes in the digestive tract.
4. Chewing gum usually passes through the body in two to three days, unless it is swallowed in large amounts or with other indigestible materials, which can cause a gum bezoar or a blockage.
5. Sleeping on the left side of the body can help with acid reflux or heartburn by keeping the stomach below the esophagus and preventing the acid from moving up.
6. Sleeping on the left side of the body can also help pregnant women in the second and third trimester by avoiding compression of the inferior vena cava, a large vein that carries blood from the lower body to the heart.
