So say I buy a slice of pizza. I consider this my first slice of pizza, but i definitely have had pizza before. I go to the counter and buy another slice of pizza and i would call this my second slice. How long after the first slice is consumed does the next slice count as my first one? |||I would say your next meal.|||interesting question. I would say about 5 hours. because then it would be your first piece of pizza for that meal. or maybe 3 hours if you eat meals that close together. Good Q though.|||oh - about 5 minutes :)
