You are unusually protective of your thread, @marvin100 , and a need to quote yourself. That’s kinda funny. For whatever reason you want to argue with what the result boils down to. The bottom line is that the primary variable is $. Perhaps you’d prefer to go back to arguing with the posters who are feeling that anecdotal evidence is more valuable in this discussion. All I said, and I won’t quote myself in a quote box, is that this is not news. Sorry you are having such trouble with that. It wasn’t an argument. It was an observation. But you seem to want to put your boxing gloves on.
Glad the investigators did a longitudinal study supporting known past results.
Perhaps you would prefer to shadow box.
