I've come to be scared of the common greeting phrase "how are you?". Often the answer will be something not very positive which is never what anyone wants when asking that question. And I don't want to ask it of people incase they ask it back which makes me much less polite that I ought to be.
The other day one of my friends asked a different question "What's it Like to Have a Brain Injury?" which was not something that anyone had asked in a year of having it. It struck as an interesting question. My answer (the first thing I could think of) was that it was like aging 40 years instantly. What's yours?
