Back from walk. Safe and sound. Rarely feel uncomfortable out and about at this hour. Guess i live in a relatively quiet neighborhood. Hmmm... solving the problem of fake news actually could be more useful than any of the above, well perhaps a mite under world peace. Sure, go for that problem! It's not what we don't know that gets us, it's what we know that just ain't so. (i am sure i am paraphrasing someone, but too lazy to track down who) I look forward to your results.
