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.

RE: How long does mayo last at room temp? Okay, so I wanted to have a tuna and mayo with crackers for lunch tomorrow at school, but i don&#39;t want to get samonella from the mayo being at room temp too long.How long will it last before it goes bad?ayo is made with raw eggs, but the mayo you buy in the store is pasturized so it will not spoil so fast. When any food is held at room temperature the bacteria doubles every half hour. You are better off using a cooked salad dressing like Miracle Whip to take in your lunch.
