The video features a doctor answering various medical questions from viewers. Some of the questions and answers include:
* It's not recommended to sleep next to a WiFi router, as it's not good for your health, although there's no concrete evidence to prove it's dangerous.
* Drinking blood can cause GI disturbances, constipation, and inflammation in the GI tract.
* Holding in poop is normal, but overdoing it can cause nausea, vomiting, and constipation.
* Staying up all night can lead to neurological problems, such as Alzheimer's and dementia, due to the lack of respect for sleep.
* Motion sickness can occur in different ways, such as in VR or in an automobile, due to a disconnect between what the body is feeling and what the eyes are seeing.
* Waking up early can cause indigestion due to the body's shift from rest to fight or flight mode.
* An allergy is a histamine-driven response, while an intolerance is when something doesn't agree with the body, such as lactose intolerance.
* Pubic hair is curly due to its type and the fact that it helps to lock in pheromones, which were an advantage for early humans.
* Smelling salts work by irritating the nasal receptors, which sends a shock response to the brain and wakes a person up.
* There are limited ways to minimize the appearance of scars, with the most effective methods being lasers and surgical approaches.
* Shaving certain areas of the body, such as the pubic region, can increase the risk of STIs and infections.
* When a person needs a knee or hip replacement, doctors use measurements and x-rays to determine the right size.
* Surgeons send removed tumors to pathology for analysis to determine the type of tumor and whether all cancer cells have been removed.
* Humans can get itchy due to various reasons, including physical or chemical reactions, and nerve misfires.
The video also includes a promotion for ShipStation, a shipping software company, and encourages viewers to pursue a career in nursing despite a fear of needles, as it can be overcome with medical treatment and therapy.

17. There are limited ways to minimize the appearance of scars, mostly through lasers and surgical approaches.
18. Removing scars can only be done surgically or with a laser.
19. Orthopedic surgeons use measurements and trial different sizes to determine the right size for knee or hip replacements.
20. Surgeons send tumors to pathology for analysis through microscopy to determine the type of tumor and its characteristics.
21. Humans can get itchy due to physical or chemical reactions, or nerve misfires.
22. A fear of needles can be overcome with medical treatments and therapies, and should not prevent someone from pursuing a career in nursing.
