What is love? Scientists explain it in terms of the body’s release of adrenaline, dopamine and serotonin; cynics refute its existence by citing ancient philosophy.

Parents across the country are in Valentine’s Day scramble-mode, rounding up enough treats and cards for all their kids’ classmates. Holidays are such work for parents. And expensive too–the National Retail Federation says Americans who celebrate Valentine’s this year plan to spend nearly $200 on average. That includes gifts for a special someone, but also kids, friends, family members, co-workers and pets. Valentine’s Day, above all, is a triumph of marketing.

From candy canes to mulled wine, Christmas is a chance to indulge in certain taste traditions.
