Spice Girls Every Month was a magazine that focused on, as you can probably guess, the Spice Girls.
In the January 1999 edition, the group was asked the question, Do you ever ask yourself what the meaning of life is, above money, fame or family? There answer:
Emma: And Health.
Mel C: Yes, it is happiness.
There we have it. As we've seen in other interviews, often the answers are terse and not very in-depth. But we have an answer nevertheless.
