P.S. I'll be hit by this. I can probably avoid it with workouts daily and/or one meal a day. LOL.
I've got photographs back four generations on the German/Dutch side and every male looks like a damn linebacker past age 22 or so. Most before. I was relatively "skinny" for my family and was pushing the underside of 200 at high school graduation at 5' 11" and a 16" neck. Wasn't an ounce of fat on me back then.
Today I can push the BMI number down into the top of the overweight range but it turns to muscle and my neck just might hit 17" then. To get out of the overweight range I'd have to be put in a prison camp with dysentery for a year, eating soup, from what I've read. I wasn't at or below 177 past freshman year of high school.
We got the "wide" genes. Nice folks say "broad". Some folks might say "redneck". LOL !
I'm also in the oddball 10% or whatever that usually ends up sleeping on my stomach in a face plant. I've always dreaded a diagnosis that requires a CPAP because I'd just end up sleeping on top of the hose with the mask smashed into or completely off of my face. I can fall asleep on my side, but once I'm "out", I could probably roll face down and break a mask or fitting or whatever and never wake up doing it. Every night.
Heavy sleeper is an understatement for me. I'd be one of those people who'd sleep through a plane hitting the house. I go from awake to "gone" and have been known to hold what others thought were full conversations in my sleep when someone thought they woke me up. The only way they can tell is that I make no sense whatsoever. Karen knows this and knows she's only halfway to waking me up if I've sat up in bed and am talking to her but making zero sense. I'd love to see a video of this. I've had it described to me by mom, dad, Karen, and anyone who's woken me up out of deep sleep around the three or four hour mark. Apparently I carry full sentences that almost sound right but can't logically be right. I can answer simple questions too. I never remember these conversations other than a fleeting feeling that I talked to the person. Eyes open and everything.
To work my on-call career the only sound I've trained myself to wake up for is an old fashioned bell ringing telephone. If I have to use an alarm clock in anger (less than five hours of sleep) it has to be a windup bell type.
Otherwise, if I hit 5-6 hours asleep, you can wake me right up. No problem. I won't like you, but I'll wake.
A few other electronic alarm types work too but they're well above the jet engine dB threshold and anyone who's experienced them who sleeps lighter usually reports mild heart palpitations when they go off. Heh.
My home security system is painful on purpose, and integrated with my smoke, CO, water leak, and freezing temperature detectors. Those who've set any of those off by accident, are usually next seen holding their fingers in their ears in shock and awe.
I recommend not burning the toast if you visit.
I usually sleep through the first few waves of radial engines departing for dawn patrol at OSH in a tent. Especially if I stayed up until.3 AM wandering around with Kent.
I do snore intermittently and sometimes it's "freight train" quality. However it seems to be more dependent upon how my face plant worked out than consistent. I've joked that I'd probably sleep perfectly silently with a circular face pillow or on one if those massage tables you stick your face in. But they suck if you're on your side for a bit. Good way to end up with a week long neck ache. A face sized hole in the mattress would be nice. LOL! Sometimes I'll find the pillow gone and I'm in a real face plant. Other popular positions are sleeping with my head on one arm and waking up to it being so asleep I can barely move it. Ha.
Love those massage table face holder things whenever I've gotten a professional massage. Heh. A "daytime wakefulness" test on one of those would be hard but mostly because being on my stomach and warm would trigger my "this is how I fall asleep" thoughts than from being sleep-deprived. Especially the fancy heated variety. Ooh. It's nap time?!
Nice. Oh, ouch... WTF ? Oh yeah I did ask for a deep tissue massage didn't I ? Holy crap! That's a pressure point! Ahhh... There it released. Muuuuuch better.
And back when I had long hair and didn't buzz cut it, I had some incredible "bed head". I still can get either the left side or right side to look like I have a bald patch and hair standing straight up on one side with the face plant.
My face plant sleep style would be incredibly difficult or impossible with a mask on.
