lastraw on "previous link in category showing same current posts"

Thanks middle sister (5 months later!) but I'm not sure how this would integrate with the code that's there now?

<?php

    // calling the header.php
    get_header();

?>

<div id="box-wide">
<?php query_posts('category_name=life'); ?>

<?php if(have_posts()) : ?><?php while(have_posts()) : the_post(); ?>

<div class="post">

<h3><a>"><?php the_title(); ?></a></h3>

<div class="entry">

<?php the_content(); ?>

</div>

</div>

<?php endwhile; ?>
<?php endif; ?>

<div class="navigation">

<?php global $wp_query; $total_pages = $wp_query->max_num_pages; if ( $total_pages > 1 ) { ?>
				<div id="nav-below" class="navigation">
					<div class="nav-previous"><?php next_posts_link(__( '<span class="meta-nav">&larr;</span> Older posts' )) ?></div>
					<div class="nav-next"><?php previous_posts_link(__( 'Newer posts <span class="meta-nav">&rarr;</span>' )) ?></div>
				</div><!-- #nav-below -->
<?php } ?>		

</div>

</div>

<?php get_footer(); ?>

</body>

</html>
