Should I eat some more fish pie?

It's delicious. It has mash potato with white sauce and pieces of salmon cooked in the oven. I already had one helping but I can't help but speculate on the ramifications of indulging in another. As the late astronomer Carl Sagan said: "If you want to make an apple pie from scratch, you must first create the universe". I'm sure the same applies to all forms of pie, but I'm not sure how relevant that is to my question. What do you think? Time is of the essence.
