Ask HN: Is Hacker News becoming more medical/health related?

I'm not sure when this trend started but it seems to me that a lot of articles that hit the front page are more medically or health related, especially on the weekends.

Just this morning I see:

Feds probing roughly 5k pilots suspected of withholding major health issues

Ask HN: My mother is slowly looking her eyesight, how to prepare?

A new method to reprogram human cells to better mimic embryonic stem cells

Federal study links testicular cancer to ‘forever chemicals’

‘Oh my God’: live worm found in Australian woman’s brain in worldfirst discovery

On being ready to die, and yet also now being able to swallow ice cream

Is anyone else seeing this trend?

If so, why do we think this is happening?
