Pages pulling my headlines

I have a website and in the header.php I have this:

<?php query_posts('page_id=35'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php the_content('<p class="serif">Read the rest of this page &raquo;</p>'); ?>
<?php endwhile; endif; ?>

The code above pulls a post.

For all sub pages (page.php) i use the following code:

<h1> <?php the_title();?></h1>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php the_content('<p class="serif">Read the rest of this page &raquo;</p>'); ?>
<?php endwhile; endif; ?>

When you view pages it will not show what is suppose to be on that page it instead shows whats suppose to be in the header.php.

Any idea what I am suppose to use to pull posts or pages if I want to include it in the header?
