Are exchanges accepted?

I'm considering applying for a refund, or at least an exchange, on my immune system. I'm sicker than a dog, and it's hit me like Katrina.

I was sick for two weeks at Christmas, and then finally got better, though I was never completely over it. I went in to the doc last Wednesday to check on the cough that never really went away, and then over the weekend, I felt it taking over again. Now, I can hardly talk, I'm hacking up a lung, and I have what they would call a general "malaise."

I did a little googling on the common cold, and I read that most adults have three or four colds a year, at the most. Some guy at work told me that he hasn't been sick for six years. I get between eight and ten colds a year, and they stick around! It mystifies me.

I'm wondering if I have too much dust floating around the house, and so it gets my allergies going, and thus wears down my immunity. I think I'm going to have the ducts cleaned, and then get an air purifier.

I might have to call in sick to work this week, if this keeps up, and that's a real bummer. I've been really looking forward to this concert, but if you start hacking every time you breathe, that becomes a deal breaker for brass players.
