most of North America is back to school season right now. If his kids are old enough then they would probably be starting. And back to school kids pass germs around like its their job.Well, it's gotten a little worse if you ask me, but he's got three small kids and at that age children just are sick a couple of times a year. If you've got three of them, there's a decent change you'll get some of that, too.
I mean, there's really little one can do and as said above, I don't think there are many people who want to listen to him when he sounds terrible.
