2 macks down in one weekend.  Count your blessings people.  Seriously.  According to CNN:

Relatives found Hayes, 65, unconscious in his home next to a still-running treadmill, said Steve Shular, a spokesman for the Shelby County Sheriff's Department.

 

Paramedics attempted to revive him and took him to a hospital, where he was pronounced dead shortly after 2 p.m., the sheriff's department said.

 

No foul play is suspected, the agency said in a written statement.
