It is all relative, diet can kill you, stress can kill you, meds can kill . Sometimes the gains out weigh the risks. SO many things have side effects and risks that we use and do each day. They all become quality of life choices at some point.
Lets just agree to disagree now that we have put the information out for others to make their own choices, OK?
