Great train of thought! Aikido is a soft art, as in it is fluent and uses only the effort put forth by your opponent. The general rule of thumb is that you must learn the hard, physically brutal arts, kicking, punching and breaking before you learn a soft art because it is very difficult to become proficient in a soft art then try and learn a hard art. But if you are hard first and learn to be soft thats just a thing of beauty!
Oh and for myself I'm a practicing Aikijujutsu (Aikido, Judo, and Karate)student of 19yrs. I prefer being a student than being an instructor however I have learned very much from both.
