Hi friendnky,
I think the database is a great idea,
but I have a question about the table.
What is 'age of onset'?

Is it the number of years of having symptoms before being diagnosed with AS?
-or -
Is it the age at which we were diagnosed with AS?

I feel embarrased for asking this.

Thanks,
James
