'Jeopardy!' Host Alex Trebek Has Mild Heart Attack
Alex Trebek, the long-time host of TV's 'Jeopardy!,' suffered a mild heart attack on Saturday, according to a statement released Sunday by the show's distributor, Sony Television.
Trebek, 71, is being treated at Cedars-Sinai Medical Center in Los Angeles, Sony spokeswoman Paula Askanas told The New York Times.
A statement released Sunday by Sony said that Trebek "is in good spirits and is currently under observation and undergoing further testing. He is expected to fully recover and be back at Jeopardy! when production begins taping in July for the new season, the show's 29th."
According to the Times, Trebek had a prior heart attack in 2007 but returned to work quickly.
Low Testosterone Not Part of Normal Aging: Study
Factors other than aging are likely responsible for the drop in testosterone some older men experience, a new study finds.
Researchers in Australia tracked the testosterone levels of more than 1,500 men, ages 35 to 80, who had their testosterone levels sampled at clinic visits spaced five years apart, UPI reported.
The study found that testosterone levels didn't undergo a steep decline -- instead they only fell less than 1 percent per year. And certain health or lifestyle factors seemed linked to those slight declines.
"Men who had declines in testosterone were more likely to be those who became obese, had stopped smoking or were depressed at either clinic visit," lead author Dr. Gary Wittert, professor of medicine at the University of Adelaide in Adelaide, said in a statement. "While stopping smoking may be a cause of a slight decrease in testosterone, the benefit of quitting smoking is huge."
Wittert and his team believe, therefore, that a drop in testosterone is not an inevitable part of the aging process in men.
The study was presented at the Endocrine Society's 94th annual meeting in Houston.
