Now I understand!

Came across this in an anthology on fishing by Jeremy Paxman called 'Fish, Fishing and the Meaning of Life';


"A recent survey showed that roughly two-thirds of all fishermen never eat fish.  This should surprise nobody.  Fish is brain food.  People who eat fish have large, well-developed brains.  People with large, well-developed brains don't fish.  It's that simple."  

Ed Zern, To Hell With Fishing, 1945.

I'll let you draw your own conclusions.
