Userage in Profile was a Hack by boofo, but it is now a default feature
The Code is pretty simple:

PHP Code:

$bday = explode('-', $userinfo['birthday']);

$year = vbdate('Y', TIMENOW, false, false);
$month = vbdate('n', TIMENOW, false, false);
$day = vbdate('j', TIMENOW, false, false);
if ($year > $bday[2] AND $bday[2] != '0000')
{
    $userinfo['age'] = $year - $bday[2];
    if ($month < $bday[0] OR ($month == $bday[0] AND $day < $bday[1]))
    {
        $userinfo['age']--;
    }

    if ($userinfo['age'] > 101)
    {
        // Are there peoply who are 101 or older and use vBulletin? Doubt so ...
        $show['age'] = false;
    }
    else
    {
        $show['age'] = true;
    }
}
