The chance of divorce is actually closer to 25% these days! Also, the original 50% figure was heavily skewed by people who had divorced previously, just FYI.
I found out today a moron I went to grad school with published a successful book. He's also an "important" person's son, though, so it's less of a jealous thing more of the "this world's fucked" thing.
My PhD isn't super useful though so yeah, throw it in the remorse file.
