I think Aikido is good for everyone. The considerations on proper use of techniques in real life, personalities and attitudes are not essential. The way Aikido is taught by any particular Sensei is the key point of Aikido education. If we agree on right educational system applied, then I fully agree with ones who think that Aikido is nearly the ideal system for the training of body and spirit. The Budo roots and spiritual background of Aikido guarantees the right approach to a system.
