It may be, as claimed, that decedent was a very old and infirm man physically, suffering from the disease of diabetes, but that would not mean that he had not the mental capacity to understand the business he was engaged in, the extent of his property, and the names of the persons dependent upon him; and the mental capacity to retain facts long enough to preserve and understand their relation to each other and to be able to form a reasonable judgment as to them." Testator's will was written by a reputable attorney. Court refused to disregard the jury's finding and hesitantly affirmed.
