My friends died in their late thirties / early forties. I don't know all the details. One guy's liver gave out - another got into pills and I'm not sure what else. I don't know what killed the others, just that alcohol was contributor. Stories like these are not uncommon. CDC says alcohol kills 80K people annually.
