I have CF friends, a bunch from CF walks, and a couple I've met in the hospital, as far as getting sick from each other and stuff, well it hasn't happened yet and I don't think it will, I mean they used to have CF camps for crying out loud! But yeah, I hang out with CF-ers and even visit them in the hospital, I think it's a great way to learn more about yourself and others, and it's so cool to see other people like taking enzymes & doing treatments, but I love it & strongly recomend it.
