Sleep Apnea. It's a silent killer.
Breathing pauses can last from a few seconds to minutes. They may occur 30 times or more an hour. Typically, normal breathing then starts again, sometimes with a loud snort or choking sound.
Thankfully I do not have it. Mostly it's do to overweight, and smoking. Most people that have sleep apnea die a life very soon, like south of 50.
I wish you well. If you suffer from this issue see a specialist.
