Teen Boy Suffers Serious Burns After 'Hot Water Challenge'
An Indianapolis teen suffered serious burns after his friends poured boiling hot water on him as part of fad called the "Hot Water Challenge."
The boiling water was poured on Kyland Clark, 15, as he slept and he suffered second-degree burns to his body and face, Fox News reported.
The incident occurred after Clark and his friends had watched videos of the challenge on YouTube.
"My skin just fell off my chest, and then I looked in the mirror and I had skin falling off here and, on my face," he told Fox 59.
Clark spent a week in the hospital. His doctors are hopeful that pigment will return in Clark's face within a few months.
"If your friends are telling you to do this, they aren't good friends," said Dr. Ed Bartkus, Indiana University Health, Fox News reported.
He said boiling hot water can cause permanent disfigurement or damage the airway. Last summer, an 11-year-old girl in New York suffered face and chest burns after friends poured hot water on her.
Also last summer, an 8-year-old girl suffered fatal throat injuries after she tried to drink boiling water through a straw, Fox News reported.
Sanders' 'Medicare For All Plan' Could Cost $32.6 Trillion: Analysis
U.S. government health care spending would rise by $32.6 trillion over 10 years under the "Medicare for all" plan proposed by Sen. Bernie Sanders, according to an analysis from a conservative-funded policy center.
Under Sanders' plan, all U.S. residents would have health coverage, with no copays or deductibles, and private insurers would be restricted to a minor role, the Associated Press reported.
The plan would lead to significant savings on administration and drug costs, but increased use of health care would lead to a sharp rise in government spending, according to an analysis being released Monday by the Mercatus Center at George Mason University in Virginia.
"Enacting something like 'Medicare for all' would be a transformative change in the size of the federal government," according to analysis author Charles Blahous.
He was a senior economic adviser to former President George W. Bush and a public trustee of Social Security and Medicare during the Obama administration, the AP reported.
Sanders noted that the Mercatus Center receives funding from the conservative Koch brothers, and that Koch Industries CEO Charles Koch is on the center's board.
"If every major country on earth can guarantee health care to all, and achieve better health outcomes, while spending substantially less per capita than we do, it is absurd for anyone to suggest that the United States cannot do the same," Sanders said in a statement, the AP reported.
"This grossly misleading and biased report is the Koch brothers response to the growing support in our country for a 'Medicare for all' program," Sanders said.
His office has not done a cost analysis, a spokesman said. The figures in the Mercatus analysis are in the range of other cost estimates for Sanders' 2016 plan, the AP reported.
