polystyrene houses that make you live longer?

Looking further into polystyrene construction I have come across a very interesting company with an incredible claim.

Dome house (Site) is a modular building created out of our favourite product.
These kit dome buildings are not only cheep and easily constructed they claim to be good for you. This is due to an antioxidant solution that is added to the expanded polystyrene



I think they are creepy.
