Sid's heart is fine. The doctor was quite impressed at how efficiently it worked: he termed it "a very athletic heart". So that's good. But they still don't know what it is that's causing his chest pain, so they're running more tests.
In other - not so great - news, the results of his second semen analysis are in, and things in that department are not looking so hot. Nothing we didn't already know, though, it just sucks to finally have confirmation.
I don't really have a lot to say about either thing, really. It is what it is.
