This is the second in a series of posts about Health Data, Health Information, and Health Wisdom. The first in the series can be found here. This is my 170th post. I starting in July 2012. I have over 2 thousand readers reading this blog as subscribers and in Twitter, Facebook, and LinkedIn from many walks of life and experiences with health care. Many wear more than one hat. Most are patients, some are family and friend caregivers, some are professionals and caregivers by trade, and some work in health technology. This series of posts is geared to everyone. I delight in trying to write for everyone. Considering health literacy while writing helps me organize and clarify my thoughts. I welcome comments and suggestions.
