Join thousands of public health professionals around the globe next Tuesday by using your iPhone or BlackBerry or whatever and chronicling public health.  May 15 is “A Day” and it’s a global event designed to create and share inspiring perspectives on daily life through photography.  Public health folks and organizations can submit photos that capture a day in the life of public health in their communities.  You can upload your photos between May 15 and the 22nd by visiting the “A Day” FAQs page (which will go live on the 15th)
