Chas its natural to be stuck and stubborn in our old ways I'm guilty of that myself to a point,.....but if new roads aren't discovered nothing gets done.....remember the great Viking Warrior Ragnarr Loðbrók's journeys to conquer new lands when no one believed in him turns out he was right,...?.....We as humans are always curious of the unknown....personally I embrace it....there will be new solid fundamentals and genuine knowledge and skills yet to come we just dont know it yet!!
