NANNY BLOOMBERG AT IT AGAIN:  NYC Mayor Michael Bloomberg isn’t satisfied with dictating what kind of oil your french fries soak in or how big your Big Gulp can be.  He’s at it again, now proposing to ban all junk food in the city’s public and private hospitals.  So if Mom is in the hospital for an operation, junior can’t be comforted with an ice cream.  Spouse battling an infection or cancer and your tummy rumbling at 4 pm?  No Snickers for you!   News flash, Mayor Bloomberg:  WE’RE ADULTS.
