Getting the 'About Me' section back after removing it

FYI – this is the one I used:

<?php
	// Callback function to remove default bio field from user profile page
	function remove_plain_bio($buffer) {
		$titles = array('#<h3>About Yourself</h3>#','#<h3>About the user</h3>#');
		$buffer=preg_replace($titles,'<h3>Password</h3>',$buffer,1);
		$biotable='#<h3>Password</h3>.+?<table.+?/tr>#s';
		$buffer=preg_replace($biotable,'<h3>Password</h3> <table class="form-table">',$buffer,1);
		return $buffer;
	}

	function profile_admin_buffer_start() { ob_start("remove_plain_bio"); }

	function profile_admin_buffer_end() { ob_end_flush(); }

	add_action('admin_head', 'profile_admin_buffer_start');
	add_action('admin_footer', 'profile_admin_buffer_end');
?>
