Or was there a systematic lifestyle change?<BR/><BR/>I'd believe either, but am leaning towards a difference in data collection. The biggest variation is due to the influenza outbreak, so it's possible the other variations correlate with other large public health issues. Perhaps post-WWII something happened in the health care space? <BR/><BR/>(edited slightly, I misread the title :)Todd Huffmanhttps://www.blogger.com/profile/10770545950354723691noreply@blogger.comtag:blogger.com,1999:blog-2797922828346897008.post-77740484868337142302008-12-22T00:17:00.000-05:002008-12-22T00:17:00.000-05:00profound and simple!profound and simple!Anonymousnoreply@blogger.com
