Longtime “Wheel of Fortune” host Pat Sajak is planning to retire next year after more than 40 years on the popular TV game show.  He made the announcement in a tweet late yesterday,  saying the upcoming 41st season will be his last.  The 76-year-old said it’s been a “wonderful ride,” adding that he’ll have more to say in the coming months.  Sajak started on “Wheel of Fortune” in 1981 alongside co-host Vanna White.  The show’s 41st season is set to begin in September.   Will you still watch after Pat leaves?
