Why not turn that frown upside down — with a shot of Botox? By preventing the physical act of frowning, the muscle-paralyzing toxin just might ease depression.

A small-scale pilot trial, published recently in the journal Dermatologic Surgery, found that Botox injected into frown lines around the mouth or in forehead furrows of 10 women eliminated depression symptoms in nine of them and reduced symptoms in the 10th.

It's nowhere near proof that Botox can treat depression, but experts, including the study's authors led by Dr. Eric Finzi, a cosmetic surgeon in Chevy Chase, Md., say it should be studied further in larger trials that can control for a placebo effect.

The study results fit with a large body of psychological research that has long shown that the mere act of smiling — even the most insincere "I don't want to pose for this photograph" smile — makes people feel better.

QUESTION: A friend referred me and several others for a music survey. Everyone who took the survey was entered into a drawing for $100 — and I won. The friend who had referred me is now upset, because she thought I should have split the $100 prize money with her. Should I have shared the prize with her?

ANSWER: Sharing the winnings would have been gracious, but it was not ethically required. When you play a game of chance, it is a given that it is luck, not merit, that determines the winner.

Your friend cannot rightly accuse you of being unfair in keeping the winnings, since you didn't have a prior agreement with her about splitting the bounty.

Anyone who would carry such a grudge is not a true friend. You won the money fair and square, so your so-called friend should grow up, take her lumps, and move on.
