Run!  Save yourself!  Medical science agrees that YOU could spontaneously combust...ESPECIALLY IF YOU'RE A WOMAN!

At least that's what they thought back in the late 18th century.  Those who know these sorts things STILL say that you could burst into flames for no particular reason, but way back then, they REALLY took this thing seriously.  From an article published in 1799, these are the six big risk factors for human spontaneous combustion: 

1. You're over 60

2. You're overweight

3. You're inactive

4. You drink

5. It's winter (?)

And, most conspicuously...

6. You're a WOMAN!
