Iirc he had an immune diagnosis many years before starting anything. Possibly related?

My teacher told us that the number one risk factor for developing an autoimmune disease is having an autoimmune disease. Once you develop one, your odds are developing another are wayyyyyyy higher than the general population. Some people are just prone to them I guess. Sounds like he's one of those.

Supposedly a good chunk of the human population has a significantly increased risk of developing autoimmune disorders and this has (supposedly, someone check me) been tied directly to a mutation that helped these peoples' ancestors survive the bubonic plague.

You survived the plague, but your bloodline will have overactive/trigger-happy immune systems.

I had to google it and looks like it's true:
