CNN reported the story of Bev Holzrichter, 56, who runs a horse stable in Charlotte, Iowa with a live stream installed for foaling season.
In 2004 one mare, Sierra was having trouble giving birth. Holzrichter went to check on her without realizing that another mare, Nifty, had broken down her door and was in Sierra's stall trying to steal her foal.
Trying to defend her newborn, Sierra kicked Holzrichter three times in the chest.
Users on the live stream watched the entire incident, and came to the rescue.
Residents of Germany, the United Kingdom, France and all over the world called the Charlotte Rescue Squad. When they arrived 45 minutes later, Holzrichter was already in shock with a dangerously low temperature.
"The Internet is my hero." Holzrichter said of her ordeal. "Those people watching are the ones who helped me. If it wasn't for the technology of the web cam, I'm not sure when I would have been found or what would have happened to me."
Holzrichter suffered a damaged knee and leg.

Silber, was suddenly struck with a disease that disfigured his body and caused him to retreat indoors, not wanting to be seen.
Doctors were unable to diagnose Silber after numerous tests.
One day, he was browsing Reddit, when he saw a posted photo that resembled his symptoms. One commenter added that the man might have Cushings Syndrome.
Upon further research Silber realized he had all the same symptoms of the disease. His doctor, however, was not convinced.
Not until Silber went to an endocrinologist did she confirm that he had Cushing's disease.
Silber was able to remove the tumor and is on the road to recovery.

A fractured ankle and surgery to repair it caused Doug Henning to be off his feet for a couple weeks.
One Sunday night, however, he woke from an excruciating pain in his left ribs and a fever.
Googling "fever after surgery" on his iPad Henning learned about a pulmonary embolism in which circulation in an immobilized leg can result in a clot. If the clot breaks off it can travel into the lungs and cause chest pain and fever.
Henning was going to ignore the signs until he read that pulmonary elbolism when left untreated is fatal.
Henning went to the ER the next day where doctors discovered a clot. Thankfully a regime of blood-thinners will cause the clot to disappear over time.
The moral of the story according to Henning, "Google is definitely your friend."
