Well this story will probably freak you out a bit.
A Nevada woman died recently of a "superbug" that is resilient to all antibiotics available in the United States. The woman in her 70s, who traveled to India frequently, had fallen and broken her femur and was in and out of hospitals for the last couple of years. She developed an infection and, despite using 26 different antibiotics, she was unable to be cured and died. Experts now fear that it is only a matter of time before this becomes more common and more "superbugs" develop resiliency to antibiotics.
So basically, stay inside and have no contact with anyone ever again!
