Liberation War : Bangladesh

I have been thinking since the sudden departure of Major Akhtar ...( may his soul rest in eternal peace)

Slowly and gradually we soon or later will be loosing all those valiant golden sons of our motherland.

But , I think it is imperative for the nation to do a research on those golden sons about a subject a grey subject ... "What was the psychological impact on those Freedom fighters during &  after the liberation war"...did they suffer any kind of battle fatigue - psychological impediments - happiness or anger or depressions? 

Which we have not collected - collated - archived - analysed - extrapolated.

I strongly feel before we loose those greatest of all heroes we must find out about their psychological health and its impact and make a profile for our future generation to learn - know - study and analyse.
