You asked us, "Do people really drill holes in their heads?"
 
Yes, apparently, they do. 
 
It's called trephination or trepanning. And it's often said to be the oldest form of surgery we have evidence for. 
 
Trepanning goes back at least 8,500 years.
 
When archaeologists discovered a bunch of Stone Age skulls in France, they were startled to find that 40 out of 120 of them had holes in them. 
 
And many of those skulls showed signs of healing, meaning the patients survived. 
 
It turns out that trepanning was once pretty widespread. 
 
In fact, the ancient Inca in South America practiced it for hundreds of years. And they eventually reached a 90 percent survival rate. 
 
In the Middle Ages, in Europe, people had holes drilled in their heads to relieve headaches and insanity. 
 
If you have migraines, you might understand the impulse to drill into your skull. But it's definitely something you don't want to do at home.
