A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

Why is Trump proposing a weird subsidy program that actually sounds like the ACA?? The truth is that Obamacare is fundamentally very conservative (Mitt Romney's plan!) and any attempt at meaningful reform can only go left ... Who will we buy health insurance from again?

Still, I do wish there was an easier way to diagnose merges w/o complicated code. GPT hasn't helped, and joyn doesn't seem to do it right. Any advice?
