After years of fighting germs, UN to focus on new global killers: heart, lung disease; cancer

What's killing us? For decades, global health leaders have focused on diseases that can spread ????? AIDS, tuberculosis, new flu bugs. They pushed for vaccines, better treatments and other ways to control germs that were only a plane ride away from seeding outbreaks anywhere in the world. Now they are turning to a new set of culprits causing what United Nations Secretary-General Ban Ki-moon calls "a public health emergency in slow motion." This time, germs aren't the target: We are, along with our bad habits like smoking, overeating and too little exercise.
