Does humidity cause head colds?

I'm sure it doesn't, but man - after several days of extremely high humidity levels around here (something we're just not accustomed to in these parts), I came down with a head cold yesterday. It's just annoying right now - keeping me from sleeping, making me sneeze incessantly, causing my nose to run ad infinitum - but I'm OD'ing on vitamin C and Zicam in an effort to keep it from getting any worse.

In other news:

• My dad was in the hospital again over the weekend, although my understanding is that he'll be coming home today. His esophagus had been growing scar tissue ever since they got rid of the cancer that had been there, and the scar tissue was closing up his throat so he couldn't swallow. The doctors were scraping away the scar tissue and ended up poking a hole in his esophagus (they apparently warned him that was a possibility). He'll go back in a week to see if the hole is healing itself, and in the meantime he can't swallow anything - including water. He's had a feeding tube back in for a few weeks now, it'd gotten so bad. I kind of wish they'd just go in and remove the offending piece of the esophagus so he can get back to a somewhat normal life - although the recovery time from that kind of surgery is weeks, it still seems like it'd be better in the long run. But I'm not the one who'd have to be in the hospital.
  
• Bub's appetite isn't back after his last chemo appointment (last Weds.), and he's due for his next round this Thursday. I'm not comfortable taking him in right now, since I don't feel like he's rebounded from the last one. I left a message for the doctor today, so we'll see what she says. The last time he went in for this same drug, they sent him home because they said his bloodwork showed he wasn't up for it. I'm wondering if it's the same situation this time. He's shedding like crazy, so the chemo is affecting his fur - it's not falling out in big clumps, but it's definitely falling out. The saddest part is he's losing his whiskers - he's only got two on the right side of his face, I noticed yesterday.
