I haven't but my mom did back when it first started. The rest of us were lucky not to catch it. She's fine now. From what she says she had a mild case.
I went through a huge wrist watch phase in 5th grade. I wore like at least two on each wrist. I was such a dork. I just thought they were neat. Now I have like a lot of them and never bother anymore.
We have to change for gym. It's a big deal for some people but I've been changing in dressing rooms for a while so I'm pretty alright. I've notices the dressing rooms people are way more comfortable in the open. But that just might be me.
