Alice,

Earlier in life I had some pretty big responsibilities with some pretty interesting problem-solving challenges, professionally; my own small part of "world peace" was included. In my post above, that "world peace" line was just my way of reminding myself that I have other priorities now-- that although the old stuff was a lot of fun, it's not on my playground so much anymore.

No, I was just kidding around that after several days of fog, pain, and poor sleep, a number of pending issues suddenly don't seem so overwhelming and it's fun to be back to what's normal for me-- inquisitive, creative thinking.

That rare cup of morning coffee didn't hurt, either, obviously. :~) On topic, caffeine in small doses has been shown to aid thinking. (The trick is SMALL, when LARGE tastes so good. Today's was a tad large.)

It's a functional phase, since what I have been doing since the last post has been a series of small but overdue housechores punctuated by chair rest. My knee, the current part under rehab, is starting to hurt and swell from the day's chores, but I know from the week's doctor visit and past experience that I need to keep moving but not overdo it-- not sit too long but sit long enough-- etc.

New anti-inflammatory regimen to work into the picture as well.

The trick of any sort of rehab is to keep moving through it depending more on logic than on short-term feelings and sensations.
