LionLegs post if fair enough. And I wasn't being that flippant - I've cut my red meat intake right down to once a week. The problem is, as I said, everything causes cancer and considering the investment in place they aren't going to rip up turf based on one study.
If we jumped to conclusions we would have cell phones banned as initially there were studies which say that they cause cancer while later studies showed that they do not.
In all likely hood it does cause cancer and something will have to be done about it, most likely a lot of places will sue the turf manufacturers that will promptly go bankrupt and communities will be lumped with the bills.
