pjo (or tk) and others: I don't know what MI is (other than Military Intelligence). Can you tell me what those "bouts" were like? When did he start getting it (after/during WW2 or during KW?) Wouldn't malarial illness keep a man from eligibility to serve in the armed forces? Did he serve in Northern France-Belgium-Germany? Take pills? Fred mr.gsd(at)netscape.com
Mr.GSD - sorry if I'm not replying correctly - I'm new to the forum world 
- I tried to quote but it turned red with a negative sign - until I found this site I didn't even know why people use icons. To answer your question about MI - it's a medical term for heart attack. My mother was a retired nurse so I tend to use some terms she used. We lost her to cancer last year. still struggling with that- I don't remember when he started being ill with malaria but I do remember many times - him in bed for days at a time with chills so bad the the bed actually shook. Mom mentioned it was ongoing after the war but I didn't ask which war. He retired in 1963 and passed away in 1972 - shortly after his 50th birthday. He served in both WW2 and Korea.
