Not worrying about health issues
at your age is one thing. But how about others? How about ignoring His Word? I quoted this previously but...maybe you overlooked it?
Matthew 5:17-19 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Surely you don't think that refers to literal poison? I assure you...we will definitely die should we drink a cup of arsenic.
