Serendipity is with us....

Today, a link on refdesk.com took me to this page, which discusses 'Unsolved problems in physics', and lists some with *** 3 stars, as "*** Problems marked with three stars are considered by some physicists to be outside the purview of physics, more properly philosophical in nature".
That's kinda why I didn't answer, in this context, a question about 'how I watch myself'.

scroll down to 'other problems'. (and as you scroll past 'biological problems', note that biological issues related to ongoing discussions here have NOT (yet) been listed as 'unsolvable').

I have only been looking at that page for 10 minutes, and already my brain is tired. ☺
