I've thought about rejoining a gym but I have some concerns. I have read that MRSA is on the rise in gym settings, and as we all know, MSRA one of the big bugs that we all strive to avoid. The study I read was just about the prevelence in normal people. I suspect if the study was just of CFers (and it wasn't), the numbers would be even greater since we are comprimised. So I am not sure if it is worth the risk.
