@markarayner Interesting but I disagree with it. Tradition doesn't have to be old enough to have dead people associated with it. What makes it traditional is not how long it's been done, it's that people do it because they feel it should be done. Maybe because they've been told so. And that strikes me as peer pressure from the present day.

"You're not cooking sweet potato casserole this year? But it's TRADITIONAL!" That's not a dead person applying the pressure.
