Roast Dinner!?!
Answers: Why do we all want to sleep after eating a Roast Dinner??
I believe it's because blood is diverted from other parts of your body, your brain for instance, to your digestive system.
This causes drowsiness and an urge to flop down on the sofa and zonk out for a couple of hours.
cos were all fat greedy b*****s who eat to much! being full makes us sleepy!
i never want to :S that jus weirdness but maybe because sundays are boring
To help digest it , as do snakes after a big meal, not that they eat sunday dinner of course or acctually bother to cook the meat,lol,
Eaten too much
Um I dont think its just after we've eaten alot.. cos dont lie people who doesnt have more on their roast dinner then they do normally. i know i have more on roast dinner day :) So its prob cos we've eaten so much our bodys need to like work it off or something.
i never do mayb its coz i take 2hrs to eat it ahaha
i did know the answer to this but have forgotten, if it comes back to me i will edit my answer
Your body wants to shut down to digest all that food.
