Has anybody used their martial arts training in a real life situation? - anybody used photographik

I think, to learn Aikido. I do not know how effective it is when I use a real life situation. Has anyone ever used aikido in a real situation? Or maybe someone has a different form of martial art, used in a situation? Just curious, how martial arts can be seen to be truly effective in self-defense seriously.
