Remember that the pursuit of happiness, in the Declaration, is not a quest or a pastime, but an unalienable right.. Everyone has the right to actually be happy, not just try to be happy. To use a metaphor: You don't just get the chance to make the baseball team, you are guaranteed a spot.
How long does an unopened package of mayonnaise last at room temperature? Properly stored, an unopened package of mayonnaise will generally stay at best quality for about 3 to 4 months after the date on the package.
As long as the bottle is unopened and stored in a cool place, it should be of best quality for at least two years, possibly longer. Of course the quality drops gradually, so itâs not like the mustard wonât good a day or two after those two years.
