The good news is your ancestors survived the bubonic plague. The bad news is they may have left you vulnerable to other diseases.

If your forefathers somehow managed to avoid getting snookered by the Black Death back in the Middle Ages...

...well, that's good, because otherwise you wouldn't be here!

The downside is that you may have some upcoming health trials and you should at least be aware of that.

The Black Death, the world's most devastating plague outbreak, killed half of medieval Europe's population in the space of seven years in the 14th century, shifting the course of human history.

But what about the survivors of what remains the single greatest mortality event ever recorded? New research published Wednesday in the journal Nature suggests it was more than luck that determined who lived and who died.

Analysis of centuries-old DNA from both victims and survivors of the Black Death has identified key genetic differences that helped people survive the plague, according to a study published in the journal Nature.

These genetic differences continue to shape human immune systems today, with genes that once conferred protection against the plague now linked to a greater vulnerability to autoimmune diseases such as Crohn's and rheumatoid arthritis, the study said.

Now, you might be tempted to respond to this by claiming:

...but it's worth pointing out that the Black Death had a fatality rate of upwards of 60%, while those other diseases, while no picnic, are, well, just a skosh less dangerous than that.

Life's full of trade-offs. At least we're living in the 21st century.
