Re: how many people practice aikido?
This number is way too hard to compile. Even if you were to collectively gather information from every Aikido Dojo that was listed in the yellow pages, you would still have those that taught in their garage, to family only, or to friends they come across.
You also have those of us that have trained in Aikido, but train in other arts now........
The number it too hard to attain. I am sure there are those out there that can try to estimate, but the number is going to be way off.
