Internet is wrong.

I just found this on "HEALTH LINE", the internet has answers to anything and everything. "Both sinus bradycardia and sinus arrhythmia may commonly occur during sleep. Sinus bradycardia can be a sign of a healthy heart." Trained athletes, especially endurance, marathon, some young people and people such as sponge and pearl drivers. Don't be alarmed, a doctor will order thousands of dollars of tests, prescribe many pills, suggest a bland tasteless diet and refer him other doctors so they can make some money too? Too cynical? 😎
