It seems like you keep asking this same question in many different threads. Can you please refrain from starting multiple threads on the same subject?
I have merged the two threads that you have recently started.
I will note, too, that you have asked this question here on AikiWeb seven years ago as well which leads me to be curious about your intentions behind starting these threads.
i was just wondering how long it takes aikido to work because when i tried to perform an aikido technique on my dad he resisted and did not work.
so i was just wondering how long it takes aikido to work in real self defence situation.
If after seven years you can not do a technique sucessfully on your dad, you should give it up.
