I dont know, these are things that are pretty personal. And unless you get to know someone really well, they might not be willing to share.

It took a while before one of my FC friends told us she was deaf. We were all completely fine with it. But the main point was that she didnt want anyone to think diffirently of her or act diffirently towards her.

I bet it's that way for a lot of people. Especially those with chronic illnesses.

Do they play? I have no doubt that they do. But dont expect them to shout it off the roofs that they do.
