Chickenpox ... in adults?

TV personality Barbara Walters made news this week when she developed chickenpox after first having a bad fall.  It turns out that she never had the disease as a child, making her still susceptible even in her 80s.  I was asked to comment about adults getting chickenpox in this article:

Lots of topic covered, with the bottom line being, you really don't want to get this disease!
