Thanksgiving usually means we’re going big — way over the top. Twice the size bird we could possibly eat. More side dishes than the table can hold, and of course, so much pie. We travel great distances to see our families and friends — we hug, we eat, we argue, and we nap. On this special episode of The Pulse, we explore the traditions and rituals of Thanksgiving through a scientific lens. We hear stories about the neuroscience of gratitude — and how it can help us through grief; the environmental impact of our holiday feasts, from cranberries to food waste; and ask whether turkeys are really as dumb as they look.
