Well, here it is, 04.50 AM and I've read through the interchange of messages. Oh, MY!
I sensed, frustration, downright anger, bewilderment, logic at a brick wall and not least of all, tiredness. (goodness knows what he did to himself while off with family. )
Will big corporations never learn about tiredness? It cost American companies $117.000.000.000 in IIRC 2017 Big university studies. A lot of men denying themselves sleep WILL produce substandard results. I have the publication ISP. Fear and overwork will produce . . . well, a MAX? and a lot of other tidying up to do.
Treat tiredness with the mos routinely sold seeping aid in North America, and you'll start to kill people. It'll be hard to stop as the money involved is right up there in the big league. A different subject, but the death toll is stunning. I'll look up the data on the morrow. Not so dramatic as an aircrash, but a lot more consistent.
