[Individual Unemployability]

I am 75 years old retired from the USN. I met the IU requirement with 60, 40, 20. I am am at 80% now. I filed for IU and was denied and the reason for denial is : i have reached 4th year of college and have worked as an office personnel office during my military service. I have also received electrical and technical training during my military service. VA examination results DO NOT SHOW symptoms or manifestations that are so severe to render me incapable obtaining and retaining gainfull occupation in an office setting. I am preparing a letter of consideration to my denied IU claim. What will be your recommendation and arguments to put on my letter. Who will hire me at age 75 and residing in the philippines.
