table overhead

[Roost3r]

i read that table overhead happens when you delete or update a lot of information; i do this regularly; are my tables made bad or do i just need to optimize my table frequently

Here's what I've done:

function optimize ($what){
mysql_query ("OPTIMIZE TABLE $what");
}

Then after I've done all my delete queries, I run optimize ("tableName");
