Farmer thinks for a bit and replies, "Well, I wouldn't start from here."

When asked, most people (72.4%) living near lynx in Norway say they LIKE living with lynx. Just 8.3% say they dislike lynx. In Scotland, where we're currently denied the opportunity to live near lynx, the majority of people WANT to see lynx reintroduced.

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.

The fundamental problem:
58% of voters want public spending maintained or increased.
67% want taxes to stay at their current level or be cut.
In reality, it’s a binary choice. Taxes go up, or spending is cut. That’s it.

The word ‘harbour’ shares its origin with French ‘auberge’ and German ‘Herberge’ (both “hostel”).
They come from West Germanic *haribergu (military camp), a compound of *hari (army) and *bergu (shelter).
Other related English words are ‘harbinger’, ‘to harry’ and the name ‘Harold’.
