Dr. Mike answers a series of questions on various health-related topics, including:
1. Bones: They are spongy and have blood vessels, making them "wet".
2. Waking up: A slap can wake someone up, but a sternal rub is more effective.
3. Body parts: The "leg version of the armpit" is called the palpateal area.
4. Food safety: Apple seeds can be poisonous if crushed, but it takes a large amount to be harmful.
5. Dreams: Medications like Benadryl can induce vivid dreams.
6. Weight loss: Lemons have no effect on weight loss.
7. Smell and nausea: A strong, bad smell can trigger nausea as a defense mechanism.
8. Epilepsy: People with controlled epilepsy can work in hospitals.
9. Headphones: It's safer to wear over-ear headphones, and volume should be kept below 60%.
10. Protein sources: Natural sources like beans, nuts, and chicken are recommended.
11. Colds: Cold weather doesn't directly cause colds, but it can increase susceptibility.
12. CPR: Chest compressions are the most important part of CPR.
13. Salt intake: Salt is not inherently bad, but excessive consumption can be problematic for certain individuals.
14. Lightheadedness: Orthostatic hypotension can cause dizziness when standing up too quickly.
15. Blood pressure: High blood pressure can be diagnosed with multiple measurements, not just one.
16. Jaw trainers: Overusing these devices can lead to TMJ problems and teeth grinding.
These answers are interspersed with personal anecdotes and humorous comments from Dr. Mike.
