When I had a rotary phone I didn’t have net brain drain, only time I read the words Dead zone it was a title of a film.
See this meme
I fully understand it
I’ll explain it
see it’s like this, now I live on the edge of a DEAD zone
which is techno talk for cell service
I thank GOD for the Earth’s rotation every night
which translates to LOSS of signal
No, I suspect it would be more along the lines of this
