Did the Facebook organ donor thing, although I'm pretty sure I have it in my living will and on my drivers license.

Gave me the idea for Facebook to show your/our vaccination status too. It may boost vaccination levels, which would be good with the increasing rates of measles and pertussis we are seeing these days.

And you can actually already do it. Add Life Event > Health & Wellness > Other Life Event... => Tdap #vaccines to #facebook if you are protected. You can add other vaccines too or add your kids' vaccines when they get them.
