When discussing leftovers...

Well for starters, how long can your reasonably store your food before it becomes too risky to consider eating? According the the United States Department of Agriculture, most meals are good up to 4 days later. If you want to get more technical, they have a list of foods ranging specifically from bacon to fully cooked ham, temperature charts, and correlating days (or months!) that you may safely keep your food.

Getting back to actually discussing leftovers though, what do you actually do with them once you have them? There are common rules on this topic that most people are likely to follow, such as, never feeding a guest leftovers if they are staying for dinner, but as for something as simple as whether or not to re-heat some of yesterday's pizza, your own personal preference is going to be quite apparent. Some use leftovers as a way to transform old dishes into a delightful new and tasty recipe, like hash from old corned beef. Others would drop dead at that consideration.

So it must be trickier than that after all! After all, our readings have class have confirmed that even up scale restaurants re-use food from the nights before with the justification that they spent good money on it and that after they are done preparing it, the customer won't know the difference anyway.

All in all, with time-limits aside, I think it's really your call as to how you want to treat your leftovers. Personally, I think some leftovers taste better than the actual dish on its first night (because the food gets to "settle" a bit longer and that adds a bit to the flavorful-ness of it), but hey, that's me.
