Switch sides every so often. When I start in the morning I can do about 5 mins on one side, but after a couple of switches I can stay like that for 30 mins. When you don’t feel comfortable switch.

Yup, strengthening the back muscles is the most important part. I got rid of my lower back pain by sitting like this for half an hour (sometimes more) after I wake up: https://lowbackpainprogram.com/wp-content/uploads/2018/09/how-to-sit-to-relieve-back-pain.jpg

At the start it’s a bit hard before the necessary muscles toughen up, but after a couple of days it’s no problem at all and that sitting pose is quite enjoyable. Thats the only lower back strengthening I do daily and for the past six months I feel the best I felt since I injured my lower back so I highly recommend it.

I’m not disagreeing with anything you said, I’d just like to add that Maillard reactions happen with all food, not just meat.
