How could it not be predictable? I get the cold/flu when I or someone in the family is exposed to someone sick and it gets passed on.

If we're all staying in the house and not going anywhere for a year, by what mechanism could we possibly get sick? Seemed predictable to me.

In any case, it's been so awesome to not be sick in over a year. With elementary school kid, it used to be I was sick every few weeks all year long. Not looking forward to going back to that kind of normal.
