  • It’s a map of the surface of one part of the brain. Imagine a Star Trek scanning beam going across your head from right to left, about where your ears are. This is a picture of half of that part of the brain (the other part is a left/right mirror image of this picture).

    So the cells along the surface of the brain here are connected to the sensory nerves in your body and this is a map showing which body parts are where. So if you move to the top of the brain it is the area where you feel sensation from your abdomen. Go further down the side and you get to arms and then hands, then face. Notice that sensitive areas of your body are much bigger (hands, face) because a lot more brain tissue is devoted to those areas.



  • the girl who only ate carrots and turned orange.

    I can confirm this is a real thing. When I was a kid my step-mother went on this fad diet that involved drinking carrot juice every day. It was this whole production where she bought a juicer and I remember multiple large bags of carrots coming in the house. There was always leftover carrot pulp in the trash, etc. Anyways she went wild with it for a time and sure enough her skin started turning slightly orange, mostly along her forearms where the skin was thin.

    That’s when the carrot juice stopped.

    So yeah she wasn’t an Oompa Loompa but it was definitely a visible change.





  • “Always” is a very definitive statement. But let me tell you that there is a lot more energy transferred into the tissues around the bullet trajectory. Watch YouTube videos of bullets going through ballistic gel to see what I mean. They don’t just punch holes in people they also have a huge cone of severely damaged tissue surrounding the hole. Also they can break into fragments going different directions and if they hit a bone can even bounce around doing more damage. You just aren’t likely to have that as much with an arrow because there is less energy and the shaft will stop it from richocheting in a different trajectory.

    Also the arrow may help slow blood loss while still in place whereas a bullet is not going to do that.

    About the only thing that a bullet has going for it over an arrow is that depending on where it is you might be able to stop the bleeding (via surgery for example) but don’t necessarily need to dig all of the bullet fragments out. I’ve seen quite a few patients who have bullet fragments retained in their body. No way you can leave part of an arrow though.
