LOL...
"Higher SPF people"....
It's actually TRUE.
http://science.howstuffworks.com/science-vs-myth/everyday-myths/redhead-anesthesia.htmRedheads might actually need to take more smack to get the same high, if it's already known that it takes 20% more aneshtesia to get them under for surgery.
I never get fully numb at the dentist, I just have to gut it out... Usually the lidocaine (they don't really use novacaine much anymore...) works well enough that it doesn't hurt... much. But it never dulls the sensations of hot/cold or the "funny bone" electric feelings the drill causes.
I also woke up during the two surgical procedures I've had during my life, first was my appendectomy when I was 19 back in '92, tried to say something into my intubation hose. Fortunately I was on my way back down already as my vitals showed I was waking up and they were turning up the gas and the ketamine or whatever it was in my IV, I was only told about it later in recovery. Now it was clear they were really worried I'd felt the whole procedure and they were feeling me out about it.
Then it happened again back in '10 when I was getting a heart Electrophysiology catheterization. I thought I was being helpful when I lifted my arm to my chest, pointed and said "
Yeah, I can feel it poking around right here... seems like you're close... The port in my thigh only hurts a little.." and the radiologist snatched my hand out of the fluoroscope, and the cardiologist barked at the nurse to push more Versed.
I hadn't realized that 20 minutes had already passed and was continuing the conversation with the doctors and nurses when I'd been put under in the first place. I remember being kind of surprised they got the catheter up into my chest so fast...
