A weird theory I have is we come from a suppressed culture. Ireland is one of the most invaded countries ever. I think the British started it very early, it could be like 800 that decided to come and show us out; and the Danes in the north. We've had a tough time and pretty much a similar culture would be the Jewish culture; they had a pretty hard time. They were being kicked around for a long, long time.
Catching fish is not a mental game between fish and angler. A 'smart' trout is only smarter than other trout, not smarter than a fisherman. An angler must take the puzzle of the day's conditions, and matching those conditions and his knowledge of the fish come up with a good catch. He competes with a concept, not with a fish's brain.
