MIKE WIERINGO PASSES AWAY - NEWSARAMA
He is only 44 years old.
Well you know that it's normal for people who are over 40 years old having a heart burning, or heart attacks or whatever problems with the heart. I am not sure if that guy died from heart attack just because he was vegetarian, there must be a casulite, you know. Sometimes people can't tell how did cause the heart attacks.
Of course I still can have heart attack even though I was vegetarian for some reason, for example, I am smoker and if I continue that, I will have a higher risk of heart attack, but at least I eat those healthy vegetarian foods help me reduce my risk of heart attack. I am a well balanced diet.
It's the way how we live, we can have risks for our health in any ways.
