This sleep apnea subject seems to come up everywhere say in the last 20 yrs or so. Before that and in my parents time and all their relatives, no such studies and people snored. A case is in it's final closing this week in Los Angeles against a sleep center for frauding over $11million.
WEIGHT LOSS seems to ring out loud and clear in all this.
And as I see it and from my own experience of taking antioxidants which helps inflammation and breathing issues my breathing is clear as a bell and I'm 81 soon. I can't imagine living without Vit C and Grape Seed Extract which I have been taking over 24 yrs.
