Instead, I aftermath up 3 hours aft Thanksgiving dinner, sprawled retired similar Robinson Crusoe connected the surviving country level nether a heap of my nephews’ toys. My garment is covered successful airy brownish stains, and greasy handprints smear my jeans.

What is it astir Thanksgiving that sends me—and millions of different Americans—into digestive oblivion? Are we each blissed retired connected turkey, oregon is determination different crushed Thanksgiving is the vacation for sloth?

You’ve astir apt heard that turkey nutrient is dripping with a sleep-inducing chemic called tryptophan. And portion it’s existent the worldly plays a portion successful sending your encephalon into slumber, saying it does truthful single-handedly is similar saying Neil Armstrong jumped to the satellite each by himself.
