Stuttering as an essay topic?

Stuttering as an essay topic? So, I do the IBDP program and our coordinator just emailed us saying we should have proposals by this Sunday for our extended essay ( a 4000 word essay that IB students do as a requirement for graduation). So I was thinking about doing the extended essay on causes of Stuttering or somehting related to it, since it's somehting I personally dealt with and is of Intrest to me. Do you think it's a good idea? And if you do/did the IB do you think this will be a good EE?
