although i am a sinner and have bad thoughts, i don't think anyone should suffer much less croak from a heart attack.
i think trappers heart attack came because iodine is an oxidant, and if your body can't make enough anti oxidants or you're not supplementing, it will oxidize the fat in your blood and clog your heart.
ive been doing a lot of anti oxidants, but you can take too much of those too.
life is about balance, as they say about alcohol in moderation. sometimes its very hard to find that balance unfortunately.
