Something I've been aware of since I was a child is that I almost never get a headache. Yes, I know what a headache is like and I have had them, but they're very mild ones. I only get one every several years - and when it happens, I take an aspirin and it's gone. Even a bang on the head or the excessive summer heat doesn't seem to trigger one.
I know how lucky I am. I know that thousands of other people have severe headaches almost all the time and they sound far more intense and painful than I've ever experienced.
I've mentioned this when I visit my doctor, and asked if there is any
institute I can approach that might be undergoing research where I can volunteer as a "research subject", just in case there's something about my physiognomy that may be responsible for this lucky effect. But I never get very far. I usually get a few strange looks followed by a shrug.
So, I'm wondering if it's normal to almost never get headaches? Or maybe my perception of being a bit "special" was also a bit delusional?
