nah i have no argument with big bang theory perse , i was only alluding to the difficulty by comparison with generalisations as almost being of equal quandery . all in all as someone said earlier here "one persons perspective " ( ok paraphrase) we cannot see it all no matter how hard we try , that was my point only. inevitably a generalisation takes place , its why records are made and why history is a subject , to how in someway we might avoid earlier errors . the fact that we still make them despite such knowledge shows we actually enjoy mistakes as much as success . ( sorry i went off on one again);)
