"I have come down with chicken pox, never having had it before,
  not knowing what exactly to expect from it. I am glad to be
  getting it now at age 25 rather than later on in life, where
  I've heard it can be more dangerous, although knowing that makes
  it no less scary." May 3, 1997 Chicken pox vaccine was released
  in the US in 1995. I got the chicken pox May 3, 1997. They
  recommended all adults get chicken pox vaccine in 1999. Do the
  date math.* It's why I'm pro-vaccine. Sometimes being early
  isn't _always_ a good thing.* It sucked. ------   Three weeks.
  Three intense weeks. Definite PTSD from it although after 18
  years, _most_ of the trauma has subsided. [the slightest itch
  would bring back waves of memories - think how many times you
  scratch yourself per day without thinking about it? Yeah. I
  thought about it. Every time.]

  I'm glad they have a vaccine for it now and the experience gave
  me empathy for many related illnesses and for sufferers in
  general... so it wasn't all bad. But still... ugh.
