What is the proper lead time for such um activities? From what I have read in the past it usually takes 20 or so hours for food to um complete its journey through us. I have no idea for other ahem emissions but I don’t think you can eat some beans and expect instantaneous tooting. Of course everyone’s mileage varies.
kimchi, greasy meats and sauerkraut - within 90 minutes. I know of what I speak! :-P
