When should i start to train?

at what age should I start to train for mixed martial arts fighting? I have been trianing fitness wise but, I need to konw when I should start trianing fighting wise. furthermore, what styles of fighting should I practice?

No better time then the present! I'd practice Ti Kwan Do, That trains body and mind.

Now.

now is the time

I have a second black belt in ti kwan do, what else is there?

A second black-belt at 14? Hmmm

I'm a 3rd degree black-belt in Aikido.

There is no time too soon to train in other styles...I would recommend Chinese Kenpo if speed and economy of movement is what your after. Aikido is great, but it's pure self-defense, not attacking...it's 'The Way of Peace'. I like it because it teaches how to defend, without unnecessary violence which can lead to law suits!!!

start as soon as you can think that you can really hanel it.a lot of people say brazilian jujis=tsi but that is mostly groundwork.what you want to do is get your opponent down not you.I say start now and train in tai kwon do.muayh thai (kickboxing) has less form and footwork so I say tsi kwon do.
