Awake. feeling chest pain. Is it my valve?  It's nearly a quarter century old.  How long do these things last? Titanium, strong, will outlive me, but what about the flesh it's anchored to? Pain is an indicator.  What's wrong?

I tick like a clock as it opens and closes, hearing  each time it skips a beat.  Doctors said it looked real good, but eight months ago, not now.

I have two diseases with the same initials.  Shouldn't there be a rule against that?  Multiple Sclerosis and Marfan Syndrome.  What an awkward pair.  

Overlapping symptoms complicating treatment.  You think they'd give me a two for one discount?
