OK: I've been buying and wrapping presents now forever. When should I stop?

When do you think women should discontinue buying, tagging, exchanging and wrapping Christmas presents? When they’re ninety? Eighty? I have some friends who now simply send checks. Don’t tell me it’s a joy because I hate it. I can’t see sending a check to my daughter and kids because they not only live fifteen miles away they also like to come over here and unwrap them!
