From the article, they aren’t quitting, they are retiring. Shutdown only accelerated the problem of how many are retiring.

15-20 daily is 5,475-7,300 per year or 40-50% of that 14,000 every year. It apparently takes 6 months to 4 years to train each one. So 15-20 a day seems unsustainable.

For me I am wondering if/realizing it may be Frequency illusion, partly from reflecting more. I do agree that reading what other people experience and understanding/listening to what I and my body need makes it seem like it is worse/more for me.
