@J.Zeb: Thanks a lot brother for encouraging me. After i was declared unfit, i underwent many tests at Armed Forces Institute of Cardiology(AFIC) in Rawalpindi. They didn't understand what the problem was any were only advising more and more tests, and in the end i was suggested for Angiography. But my family did't agreed for that. One Brigadier Surgeon also advised me not to go for that. So i left it there, but its truth that i am fully fit, and i was a good sportsman also at that time.Anyway this is the only thing causing worry to me.
