What are some NOT-fun facts?

CEOs now make almost 400 times more than the average worker

This is the worst one imo

Judith Barsi was a child voice actress who played Ducky in The Land Before Time. She died in a murder suicide perpetrated by her father.

Wow, nailed the topic right there. That’s awful!
- Yep yep yep.
This one was a gut punch when I learned it.

Toxic epidermal necrolysis is a severe form of Stevens-Johnson Syndrome. It's a life threatening skin reaction that's thought to be caused by an immune response to certain medications. The medications known to trigger TEN range from ibuprofen, certain antibiotics (penicillin being one), anticonvulsants, and steroids. We aren't sure what exactly causes it or how to stop it. One day you're taking something for your headache, a few days later you start getting painful red splotches on your skin. Once the first ones show up, they spread, often across your entire body. The redness grows and gets more painful, blisters form, and then your skin starts falling off! Everywhere! The only level of care at this point is to treat you like a severe burn patient, because that's essentially what you are. With large swathes of skin completely gone from your body, the only recourse is skin grafts and management of symptoms. Infections are common during the healing process and the prognosis isn't great. If it progresses into TEN, the odds of survival are about 50%. But don't worry, it's so rare and triggered by so many different medications it's pointless to try to avoid it. If the good Lord decides to kill you with it, there's nothing you can do about it!

I take lamotrigine for bipolar disorder. Had to watch for this every time I restart (gotta love that bipolar decision that you're fine and stop taking your meds).
Shit, it does sounds like the condition of the daughter of a customer of mine. She basically just had antibiotics given from a doctor, and then the next day all these rashes appear and started to burn her skin off, and she had to be treated just like a burn patient. Last i heard she's recovering, and the skin grow back so hopefully it get better. It's really scary to listen to her retelling of the whole thing.
The small section in the wikipedia article you link to on HIV struck me (see here).

It says that HIV increases the chances of having TEN by 1000x, reasons also unknown. I don't know if that makes sense given the pathology of HIV/AIDS, but it struck is another example of infection by pathogens having this long tail side effects that we may not know much about or be on top of (the Multiple Sclerosis and Glandular Fever thing recently being another notable one).

The trajectory of climatechange will as is unlock the cascade scenario

Pretty soon too. I love programming simulations of chaotic systems. One thing that they all seem to have in common is that there's a very fine line between fairly stable chaos and absolutely runaway crazy chaos. It's something that scientists call the edge of chaos. That's where our world and all life on it thrives. We have to be right on the knifes edge between order and disorder for complexity to emerge and stabilize.

Push the system slightly too far in one direction and things spiral out of control VERY quickly. It's not going to slowly get worse for decades.. it's going to slowly get worse then BOOM.. things will get really fucking bad really fucking fast.
Ooh, a new gamemode? Surprisingly fun sounding, if not for all the death

You have fewer male ancestors than female ones.

Is there evidence for this, or is it just something inferred from what we know about gender power dynamics and the like?

As for evidence, it seems plausible, as mitochondrial DNA and Y-Chromosomal DNA come respectively from our mothers and fathers. And so, I could imagine an analysis of mutation drift relative to known rates of mutation could make an inference on this over generations.
Explain.

Edit: (I feel like I figured out your meaning but will wait for your response)
- father-daughter incest or similar
  
  You have a unique female for every generation of your family tree, but males can show up more than once
  
  edit: thought of a situation where you could have a female repeat (a woman and her son.. she'd be mom and grandma to those offspring). so I don't know. YMMV on this one.
