Status bubbles

I think that this should have the name, age and if you are in a relationship because people wont just say "Oi You, in the red shirt".  They can say your name

It should contain medical info so that people don't have to wear medical bracelets

It would change your life because you would know a lot about someone by looking at your head
and would be easy to start a conversation.

I would not like these status bubbles because people could stalk you easily.
