I know GP trainees who have done this too. Not all our younger doctors are leaving for Australia & NZ. Some are staying here but leaving the NHS.
Somehow, the system has gone horribly wrong that this is happening.

There is a much stronger evidence base to support measles vaccination in all children and COVID vaccination during pregnancy, compared to annual COVID vaccination in healthy children.
I think this is important distinction, and we should be cautious about mixing levels of evidence in discussions.

OK, this is wild.
In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.
It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.
