Possibly.
I understand that the greatest density of *nerve endings* (which doesn't
automatically correlate with sensitivity) is the clitoris. (If you
happen to have one. Obviously.) And that's by a considerable margin.
As to which parts have the best spatial resolution, touch / pressure /
pain sensitivity, etc... well you would probably have a long argument
about that. Surely your fingertips are high up on the list, but I doubt
they're at the top. (Although surely higher than your elbow, which is
the point you were really trying to make...)

Funny you should mention that... I read about some people who conducted
an experiment where patients learned to "see" through their tongue by
having a set of electrodes connected to it. So merely reading braille
should be quite easy.

Actually, I'd prefer to not have any needles poked into me anywhere... >_<
I'm sure you'll agree with me on that point!

Yeah. Unless you play piano.

That was indeed the most likely one. I reasoned that if it was it was
probably meant as a joke. Yet, not the kind of jokes Andy normally
makes, so I was not sure I got it.

The big question is if these images are made by Americans. If it is
japanese research I assume you can trust them, if it's dutch it may be
correct too.

I prefer doing what is best for my health even if it requires for some
needle to be poked on me.
Needles have alway stressed me. The worst thing is to have to *wait*
for a long time knowing that they will give you an injection. Waiting is
stressful, you know when your abs get all tense, etc. It consumes your
blood sugar making you dizzy and feel ill.
In fact, I don't really fear the needle itself. I fear the stress, which
causes the dizziness. Which is rather ironic: Fear of the stress causes the
stress you are fearing to get.
OTOH, it has gotten much better in later years. A couple of years ago
I had two vaccine shots because I was traveling abroad (one for hepatitis A
and another for tetanus, as the old one was getting expired), and I felt
nothing. No stress, no dizziness, nothing. I felt quite manly when I could
just take the shots like nothing.
The hepatitis vaccine was one of those which consists of two parts. Half
a year later I had to take the second shot, and still I didn't get any
stress symptoms. It was cool.

I have always wondered why they do that. There are many parts of your
body where you basically don't feel any pain, or very little pain from cuts.
Why the fingertips? It sounds like one of the worst possible places to make
cuts, painwise.

I was kind of surprised at these images. I've seen similar things in
museums (i.e., in actual 3D) where the bits in question were about the
size of a finger or somewhat smaller in these pics. So, yah, ya never know.
ANd of course, this is just the physical number of nerves in the brain
dedicated to those areas. It says nothing about how they interact with
the rest, hence nothing about how "sensitive" things really are.

It's not a cut, it's more a poke. Nowadays it's almost painless, about
the same as pinching your fingertip between your fingernails (of the
other hand, of course). I'd guess it's because it's all capilaries there
(and convenient of course), so it's really unlikely to bleed long enough
to get infected or anything. I.e., it clots really fast, and if you only
need a drop or two, there you go.

Yeah, well... I'd prefer for it to not be necessary at all. But hey.

Yeah, that *is* ironic.
On the other hand, I'm depressed because nobody likes me. And how much
do you want to bet that nobody likes me because I'm always depressed all
the time?
IIRC, at school I had an injection for some vaccine or other. But that
was into the shoulder muscle. Just look the other way. It kinda stings,
but it's fine. ("Relax please." The words guaranteed to cause every
muscle in your body to become rigid with tension!)
Actually, wait... Last time I went to the dentist, he injected me with
some kind of anesthetic. That hurt quite a bit. Especially when injected
into the pulp cavity inside the tooth. Still, the worst part is
afterwards, when the drugs wear off... o_O
