Should you have rest days from cardio?

I used to think you can do as much cardio exercise as you like, and it was only weight lifting/etc that you had to have rest days from. However, I've started swimming a lot (like a mile 5 times a week) so I've joined a swimming forum.
Someone on there said that you have to have rest days from swimming as well, and put some formulas up 'proving' his theory. Is this correct?
I'd show you the formulas, but the other forum is down.

Depending on how fit you are tehy decrease, but i would say a rest day every now and then are important part of training.
Now go post this one on the fitness forum grumble grumble grumble
Innit.
Yes, you should take days off if you either feel you really need to, or if your performance is suffering and that bothers you.
But what is rest? I exercise almost every day (lifting / cycling / running) so every 4 weeks or so I just back off a little bit. Ride a little slower, run shorter distances, lift less. Some people might have to stop all exercise completely for a few days.
i currently work with some of the fittest people i have ever met (marathon runners, a semi pro rugby player and very keen fitness fans) and they only work out 4 days a week.
i tend to do 4 sessions of cv a week and a couple of short weights sessions. all to maintain the shittest physique you could imagine!!
