These acronyms are maybe out of control. What in the world is a DA, other than district attorney which I don't think was meant. And as to "dear", judging by the direct comments poeple on here make about their feelings toward their relatives, they are not all "dear".
If it is aunt, how much longer does it take to type "aunt" as compared to DA?
Regarding sleep, I second the idea that it may often be exercise related. I find that since I passed 65 or 67 or so, I must get at least 1.5-2.5 hours of aerobic type exercise- not heavy just pretty steady for an hour or so at a time, or I may wake up in early morning and have trouble going back to sleep. If I do get it, I may sleep through, or may wake up to pee sometime or other but go back to sleep and finish out the 8 hours or so.
It takes committment to get this much activity, but it pays off, at least for me.
