obsessive vacuumer?

I love to vacuum my floors, I vacuum at least 5 times a day and I'm not talking one time over I'm talking like 5 or 6 times over the whole carpet each and every time I vacuum! Josh was home tonight to witness first hand what goes on when I do my thing, he looked at me and said "babe I think you hit that spot a few times over" LOL I can't help myself anyways don't they say that it is good exercise? Hmmm... well maybe I will Google it!
