If you cant afford both then aikido.
I'm Hungarian and at the moment i'm doing boxing but i dont like it because of the many-many agressive gipsy,and the peoples are rude az fu*k.And i did aikido in my childhood(i was 4-5years)And i love japanese culture,i love everything about samurais,the honor code so everything..And im still interested in aikido and is it good for street fight?i mean when someone attacking,or eleminate the attacking person in one blow?.Im interested in your opinion guys:) Thank you!
