‘Extremely Skinny’ David Hasselhoff has a defibrillator implanted to prevent a heart attack.

David Hasselhoff is a heart attack waiting to happen, and doctors have advised him that he must slow down or risk dying prematurely.

The former Baywatch star, 66, recently had a defibrillator implanted to prevent a heart attack and expressed his concerns at a restaurant following a doctor’s appointment.

“He stated he was having his last bad meal and would have to modify his habits from then on,” an eyewitness added. “He was yakking to anyone who would listen about a vacation he was planning to Greece.”
