@OmicronData @ENirenberg @jbakcoleman @notdred It probably doesn't average that way. Some people have little exposure and haven't been infected in two years (some of this is due to lifestyle, not even deliberate avoidance). Others are out getting exposed all the time.
@OmicronData@ENirenberg@jbakcoleman@notdred可能不是这样的。有些人几乎没有接触过病毒，两年内没有感染过病毒（其中一些是因为生活方式，甚至不是故意回避）。其他人则一直暴露在外。
