Pre-existing conditions *are* covered in POV-Ray, right?

Oops, sorry.  I myself have a pre-existing condition, and I live in the 
USA, where the people in charge don't know how insurance works, and 
believe that human life should be subordinate to market^H^H^H^H^H^H 
crony capitalist forces.

P.S.  As long as I've digressed into politics, please convey my 
appreciation to Chancellor Merkel for allowing herself to be on the 
losing side of the same-sex marriage issue.  Being the leader of the 
free world must be a difficult job.

I will put this date in my diary. An American has called Germany "the 
leader of the free world ". Is that not heresy and covered under the 
Anti-American Sedition act of 1918? ;)


She has a tough job with all those strange people. The British press are 
showing a lot of photos of her with an expression of disbelief on her 
face. When she is talking to some heads of state.

For example:

Better change that date to 18 March 2017; I'm not the first.

I will win the court case if Justice Breyer or Justice Ginsburg has not 
retired by then.

No, but the first time I've heard it. But then it is all "Far away land" 
and we have our own problems with our NHS.

I didn't know about Justice Ginsburg. Eighty four! That's pushing it a bit.

Not a good outlook. :(
