Are they similar to birthday cards which teach you the concept of Einstein’s time and space? “So you are 40! Happy Birthday! Another year older. Another year wiser.”
Very educational. How would you ever know how many years you have spent on Earth if it wasn’t for those birthday cards telling you your age in years?
