That makes you at least 134years old?

I think it's just resistance of the public in general. The people out of school don't want to learn a new system and alot of things would still have to be converted from American to Metric and back. It would probably take a generation or two to work all the non-metric measurements out of the system. We can't teach just metric in the school system and teaching them both will just result in them forgetting the metrics and using the American system thats everywhere around them.

But, this thread is starting to get way off topic now.....
