I accidentally came across my middle brother's memorial (Htaw Min Paw U; official name was actually Htaw Aung Min Paw U but rarely used) while googling something-- details of his passing was he was in the hospital for severe asthma attacks, and passed away from complications unexpectedly. My mother and father (who have both passed away) told me they thought it was probably undiagnosed pneumonia that progressed too far by the time the doctor suspected the cause. As one may suspect, the medical care in those days was not at the highest level, but that's the way it goes...
I was at ISB through 6th grade, leaving Bangkok in 1966 to return to the States.
