                <p>It's a question surely as old as vanity itself: How can you look young forever? A <a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=13ve38a32/*http://www.plasticsurgery.org/Media/Press_Releases/Divorce_Antidepressants_or_Weight_GainLoss_Can_Add_Years_to_Your_Face.html" target="_new"><span class="yshortcuts" id="lw_1234301560_0">forthcoming study</span></a> in the journal <i><span class="yshortcuts" id="lw_1234301560_1">Plastic and Reconstructive Surgery</span></i>
offers one surprising idea: as you age, don't be afraid to put on a few
pounds. Fat, it turns out, can significantly smooth out wrinkles and
give you a younger-looking face. (<a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=120fp6s02/*http://www.time.com/time/health/article/0,8599,1849850,00.html" target="_new"><span class="yshortcuts" id="lw_1234301560_2">Read "Beth Teitell: On Not Looking Old."</span></a>)</p>
 
                <p>The authors of the new study, a team led by <a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=149fskprp/*http://www.uhhospitals.org/rainbowchildren/AboutRainbow/NewsRoom/DogaruTwins/MeettheRainbowTeam/DrBahmanGuyuron/tabid/2394/Default.aspx" target="_new"><span class="yshortcuts" id="lw_1234301560_3">Dr. Bahman Guyuron</span></a> of <span class="yshortcuts" id="lw_1234301560_4">Case Western Reserve University</span> in <span class="yshortcuts" id="lw_1234301560_5">Cleveland</span>, are <span class="yshortcuts" id="lw_1234301560_6">plastic surgeons</span> who study faces for a living. They analyzed photographs of the faces of 186 pairs of <span class="yshortcuts" id="lw_1234301560_7">identical twins</span> taken at the <a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=10rdp907l/*http://www.twinsdays.org/" target="_new"><span class="yshortcuts" id="lw_1234301560_8">Twins Days Festival</span></a>, a sort of twin-pride event held every summer in (naturally) <span class="yshortcuts" id="lw_1234301560_9">Twinsburg, Ohio</span>.
Because the pairs had identical genetic material, differences in how
old they looked could be attributed entirely to their behavioral
choices and environment. Guyuron's team had the twins fill out
extensive questionnaires about their lives - everything from how many
times they had married to whether they regularly used sunscreen. Then a
panel of four judges independently estimated the twins' ages by looking
at photos taken in Twinsburg. (<a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=11vsdmd1c/*http://www.time.com/time/photogallery/0,29307,1829375,00.html" target="_new"><span class="yshortcuts" id="lw_1234301560_10">See pictures from the Annual Twins Days Festival.</span></a>)</p>
 
                <p>The
Guyuron team's most interesting findings had to do with weight. Many of
the twin pairs were of similar weight, but differences in how old they
looked began to appear when one had a <a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=11r085hmq/*http://www.cdc.gov/healthyweight/assessing/bmi/index.html" target="_new"><span class="yshortcuts" id="lw_1234301560_11">body mass index (BMI)</span></a>
at least four points higher than the twin sibling. For twin pairs under
40, the heavier one looked significantly older. But surprisingly, after
40, that same four-point difference in BMI made the heavier twin look
significantly <i>younger</i>. (<a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=12oe6jgsa/*http://www.time.com/time/specials/2007/article/0,28804,1720049_1722077_1722425,00.html" target="_new"><span class="yshortcuts" id="lw_1234301560_12">Read "Aging Gracefully."</span></a>) </p>
 
                <p>The
study's authors theorize that "volume replacement" - that is, fat
filling in wrinkles - accounts for the rejuvenated appearance of the
over-40 twins. This theory was supported even more dramatically among
twins older than 55. For them, having as much as an eight-point-higher
BMI than their twin was associated with a younger appearance in the
face. (<a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=1209gt8q3/*http://www.time.com/time/health/article/0,8599,1874637,00.html" target="_new"><span class="yshortcuts" id="lw_1234301560_13">Read "A Brief History of Multiple Births."</span></a>)</p>
 
                <p>Guyuron
doesn't recommend that people gain weight just to look younger, and one
limitation of his study is that the Twinsburg photos included only
faces. If they had shown the whole body, the judges may have knocked a
couple of years off the age estimates of those who had kept a youthful
figure - and added a couple of years for those who were well fed in the
middle.</p> 
                <p>The paper also makes clear that,
weight aside, healthy living is crucial for keeping a youthful face.
The siblings who smoked and didn't wear sunscreen looked significantly
older than those who avoided cigarettes and tanning. Those twins who
had been divorced also looked older (by about 1.7 years) than the twins
who had not. (They also looked older than those who had stayed single,
which reinforces a point I made in <a href="http://us.rd.yahoo.com/dailynews/time/hl_time/storytext/08599187771700/30905916/SIG=124d9lecd/*http://www.time.com/time/magazine/article/0,9171,1587273-1,00.html" target="_new"><span class="yshortcuts" id="lw_1234301560_14">this article</span></a>: you are better off staying single than getting into a bad relationship.)</p>
 
                <p>Finally
- and this was the cruelest finding - those who had taken
antidepressants also looked older than their twins who hadn't. In other
words, if the misery of your divorce doesn't age you, your attempt to
treat it with Prozac might. Guyuron and his colleagues believe this
unjust fact has something to do with the drooping relaxation of facial
muscles that antidepressants can cause.</p> 
                <p>The
bottom line is that if you care mostly about a young-looking face,
don't smoke, don't spend time in the sun without protection, and try
not to get into a bad relationship that will make you depressed.
Instead, this summer at the beach, stay inside and have an ice cream.
Make it a double scoop.</p><p><br></p></div>
