Metric system dumbs us down.

[DumnMad]

This thought arises from another thread

Metric system is too easy - dumbs down maths in the population due lazy brainwork.
Just like paying people every week instead of monthly has bred a population that would starve if the shops weren't open 24/7.
Just like fast foods has bred a population that can't put together a healthy meal.
Just like GPS dumbs down nav skills.

Thank God for public officials who make life so difficult for freedom hunters that our brains get all the exercise we need.
