recycled candies

how much candies can a person eat in a day? i went out and bought more candies 10 pounds worth of sugar in multi colors. i still have a bag left from last year's halloween. if i ran out i will probably use those. if some one really ate a one-year-old candy and got sick from it may as well blame it on sugar not because it is a year old. to quote my old man here "expiration date is only a recommendation."
