Redheads require more anesthesia


Bask in the weirdness of this one:

Little known fact: Anesthetic requirement is increased in redheads. – “Red hair seems to be a distinct phenotype linked to anesthetic requirement in humans that can also be traced to a specific genotype.”

Weird just weird. Did I mention weird? Let’s talk about it. Comment if you think this is weird. If you don’t comment, I’ll assume you’re a redhead, and can’t respond because you’re testing your anesthetic-dose-requirement… Naughty, naughty.

    1. Okay, it does seem weird — even though redheads are often assumed to be “more sensitive.”

      But evidently things like hair color are tied to other traits. Remember the foxes at the Russian fur farm? They bred them to be tamer and easier to handle — and they ended up barking more like dogs and with very different colored coats.

    2. This has nothing to do with the above post, but I found this site about 2 days ago and have been reading alot of what you have been saying. I just figured I’d post on the most recent entry as I doubt that you’re highly likely stop back and see if anyone commented on your 2006 posts.

      I’m beyond interested in all the work you are doing. The post before this one actually had a me a little frightened at how eerily similar the feelings you were experincing were to my own. I believe that I am in the period of my life similar to the one in your own life which you described in your Lumosity review post. I am in a period of rapid self development and growth based on my own desire to have complete access to as much of my cognitive abilities as one possibly can in a single life time. That fact that you are years advanced on a journy that I am just beginning says to me that you are an invaluable resource who could drastically increase the rate at which I can progress through the early stages of this life long development.

      I myself have only begun to scratch the surface of what effects sound science, desire and sheer force of will can have on my mind. I feel as though the typical mind is so bogged down with subconscious self-doubt that life has become a constant mental struggle against forces most don’t even know exist. My desire is through constant introspection, research and hard work to bring my mind to the level we are all capable of, but, through an astounding number of mostly unrecognized hinderences, are unable to achieve.

      I want to find, alter and develop techniques that will not only benefit myself, but the human mind at large. I feel as though there may be a number of us out there who are on the verge, relatively speaking, of major discovery and unimaginable understanding that we may never reach alone. People should be allowed access to and control of themselves and I want to be a part, no matter how small, of that.

      I apologize for how long winded this all was, but when I speak about this topic I become more than a little passionate and it usually ends with a number of eye rolls or spectacarly disinterested faces. The only difference now is that I feel as though I’m speaking to someone who may care about what I have to say as opposed to those who just nod and pray for swift release in the form of a falling meteor or disgruntled ice cream truck driver.

    3. Sorry for not approving the comments sooner, guys! I’m glad you enjoyed the website. Getting a nice note like that occasionally keeps me from obeying those impulses to delete it during lulls in activity. (I’ve yet to have done that, though, and if I keep working on them maybe they’ll be something useful one day)

    4. Yea, please don’t do that. This is one of those sites that has the potential to save me years of research and testing on myself. It also has moved some of my understandings forward and shifted a number theories in what I believe is a quite positive direction.

      It’s really validating to find people who do the same kind of hard (speculative) work at self improvement through science as opposed to the general public who run out and buy the most recent ginkgo supplement advertised on TV.

    5. Since I am new to this site I am just getting to all of the posts and thus am probably going harass and annoy you by bringing up old posts. I also going to assume that if I post my responses on the actual page I’m responding to that they will not be seen since they are so old, so here goes:

      I was wondering how the spaced memory algorithm worked for you. I am also a biology major oddly enough and was wondering what your results were. Given that it is still in your favorites section, I would have to assume that they were positive. Either that or you were so disgusted with the method’s failure that you don’t want to see the it again. In the second case, I’m sorry, but MNEMOSYNE! Also, though I doubt you’d risk your GPA on a new technique, did you end up studying for your finals?

      Also, I had read your article about neurofeedback in which you put the pads “on your scalp”. I was wondering exactly what you meant by this because I assume, despite our shared desire for increased mental fitness, that most wouldn’t be too interested in it if it involves copious hair removal.

    7. Hey Jamie,
      Mnemosyne works great! It’s hard to stay motivated for it, though, when life is pulling you in a ton of different directions. But the things I used for it worked very well. I still have some of the things I memorized rote pretty well. I’ll probably use it again in the future when I need it — if, for example, I go to another country for some time and learn a new language. I’d like to do this at some point.

      So far as Neurofeedback is concerned… I haven’t touched it in a long time. No hair removal is necessary. You just kind of part the hair and put the electrodes as close to the scalp as possible.

    8. I started using anki a little over a month ago and so far I really do like it. I tend to go overboard when it comes to studying, so anki telling me what and when to study is really helpful for keeping my hours at an appropriate level.
      When you say you haven’t “touched it” do you mean that you’ve stopped using it or that you just haven’t written about it in a while?

      Also, I am very curious as to what methods have stood the test of time and which ones haven’t. I.e. Which methods are you still using now and which have you stopped using?

      Off the top of my head, here is a list of things I am currently doing:
      - Taught myself to write left handed
      - Use my left hand for as many day to day activities as possible
      - Began reteaching myself piano for dexterity and right-left hemispheric integration
      - Taking around 2-3 g of DHA and EPA total
      - Taking B12
      - Working with decreasing visual hemispheric dominance exercises
      - Daily work on lumosity (currently enrolled in memory program)

      There may be some things that I have forgotten or are done so regularly that they have become nearly subconscious, but that is a pretty good base for what I am currently doing.

    9. Hehe you got my beat. The one bizarre thing I still do is the left handed stuff. I’m very good at using my left hand on my mouse now, and in fact, it’s indistinguishable for me either right or left. If I played some PC games I might know the difference, but often which side of the PC I put my mouse on is entirely dictated by how much space I have on on side of the desk.

      I also religiously take omega-3. I’ve added vitamin D to the regimen also.

    10. Also, I was wondering what areas of the brain you have been able to activate with great strength. By this I mean the areas that you have felt the pressure or “pump” on. Thus far the only area that I can consistently activate is my right dorsolateral prefrontal cortex. There were, however, two instances in which I had a left brain “pump” in the same area, but they weren’t strong enough to clearly define the region of the brain.

      I don’t know if you even do this, but if you do I’d be interested to know what areas you’ve activated and defined and what you were doing in each instance. If you have the Brodmann area that would be really helpful as well.

      Let me know whenever you get a minute. Thanks.

    11. Speaking of neurofeedback….although you don’t use it anymore can you please tell me what neurofeedback equipment you were using while training yourself several years ago?

      I’ve wanted to take a stab at home-training myself but was overwhelmed trying to decide on a device that offered a good mix of features and sophistication without breaking the bank.

    12. Yup, it’s true. People with read hair do have a problem of going under or getting numb and require more anesthesia to do so. Also anesthesia wears off quicker.

    13. Ditto….I learned after the first serious surgery. Either put me out completely or don’t even bother at all…

    14. Affirmative, nice short post, love the community testing approach. you can try and live in a bubble, but it just isn’t… I dunno, insert a bubble word here.
