Telescopic grapping devices. Zoom for the optical sensors. Adjusting 
sensitivity of the optical sensors (the sensors itself, not just the 
iris). Manual focus possibility (both full and basic settings) for the 
optical sensors. Shapeshifting. Built-in cash printer. Telekinetics.

Should I list more? :)

One can just write in the number of the card (which is usually fully 
visible for a moment while when you pay your shoppings) and use the PIN 
(or better yet, *only* sign a piece of paper). Sure, the system will 
check for problems with your card, but since it hasn't been stolen or 
anything, there seems to be no problem.

Luckily that's still very hard with EMV-system (the cards with chips), 
while it's trivial with the magnetic cards.

The age at which woman can give birth is rather low. The age where there 
is an increases change of getting children with birth defects still 
lower. In some countries that age is coming close to the age of getting 
the first child. Furthermore I think the interfacing (both to other 
humans and to equipment) leaves a lot to be desired. But the question 
was not what I want but if there is improvement planned but not 
realized. Just to decide whether we are in alpha or in early beta.

That isn't what it used to mean, mind. Back when you had actual products 
you actually needed to work, "alpha" meant the version the QA department 
was testing, "beta" meant the version selected customers were testing 
for you, and "release" was what you actually put on the shelves.

Since people apparently don't do any QA any more, I guess someone 
decided to change the meaning for code that you publish via nightly CVS 
snapshots.

Interesting. I always thought alpha means "completely untested, might 
not even compile", whereas beta means "well, gee, I *think* it works, 
but I haven't tested it that much yet..."

I think until it becomes impossible to use the magnetic cards with a

I was under the impression that your heart *can* recover from damage. 
Similarly, you can't regrow brain cells, but the brain has an impressive 
capacity to reassign functions and regain normal functioning after 
fairly serious injury.

The ability to use my nipples to tune into JazzFM and control my  
temperature.

An enhanced EM sense would be nice, possibly another thumb, rewiring of  
our eyes, separation of waste and procreation organs, a lower error rate  
on cell duplication, separation of food and air intakes, extra nictitating  
membrane on eyes and nostrils, concious control of pain receptors as  
standard, better waste disposal management. Give me time and I'm sure I  
could come up with many more.

That's going to significantly lower upper limit on the speed of cell

OK, that's probably a good idea. In fact it would probably be beneficial

Two? Anyway I just thought an extra thumb couldcome in handy fro gripping.

reverse the receptors and get rid of the blind spot and filtering caused

No not really we already have two holes down there, just one for one  
process and transfer one to the other. As an added bonus women will stop  
complaining about men leaving the lid up or how there's always only a  
queue outside the ladies loo.

True, but if we can decrease the rate of decay that should compensate.

Although I'll admit some reports I've seen suggest that our ability to  
make complex noises derives from this cross over.

An extra transparent eyelid on our eyes to protect against dust etc. think  
crocodiles. And the ability to seal our nostrils shut which we seem to  
lose from our infancy.

But it's much easier to think if someone shut off those bloody klaxons.  
Hence my use of "conscious control" - Yes I know that is hurting, but  
unless the level of pain increases or decreases then stop telling me every  
microsecond.

For some reason, when I read "complex noises" I immediately thought of 
Blur's "Song 2".

I guess it seemed a fitting counter-example or something... ;-)

All very nice features indeed, but I would like an upgrade to my visual 
system. Being able to adjust FOV optically, and quadra or possibly 
pentachromatic (or more) visual sense expanding into the ultraviolet and 
  infrared portions of the EM spectrum. Thought it would be nice to have 
sensitivities in IR, R, Y, G, B, V, UVA, UVB (octachromatic) or have the 
color sensors in our eyes work like our ears (many, many different 
frequencies are detected individually in small increments) Though that 
would be impractical. The upshot is we'd be less susceptible to metamerism.

The human eye features two systems for adapting to light levels. One is 
the iris, which can adjust the amount of light that enters the eye. But 
in really low-light conditions, a second set of light receptors in the 
retina which respond to much lower light levels. (And don't distinguish 
colour. That's why in the dark, everything seens monochrome.)

Likewise. I can also adjust the convergence...

Yes. But, interestingly because of the chemistry of the eyes, it takes 
quite a while before night vision is effective.

So can I. As a teenager I got swept up in the whole stereogram thing. I 
used to look at pages and pages of them, and eventually went to try my 
own. Then I went for a vision test to renew my drivers license. I 
couldn't seem to match the center set of numbers normally, it actually 
took me a couple tries before I could get it right.

More precisely, because the photosensitive chemicals used for low-light 
vision get utterly saturated under normal lighting conditions, and once 
they are depleted, it takes a while to manufacture more. (Under 
low-light conditions, it gets depleted so slowly that the speed of 
manufacture isn't an issue.)

Yeah, it could possibly be improved. But given that homo sapiens is not 
a nocturnal species, the fact that we can see in the dark at all is 
fairly impressive. *Realy* nocturnal animals like cats have a wide range 
of special adaptations for low-light conditions...

>> Likewise. I can also adjust the convergence...
>

I only caught on once I finally figured out how they're actually 
supposed to work. The whole "look into it, not at it" thing didn't make 
any sense to me. When I finally realised they meant your eyes are 
supposed to hyperconverge, it suddenly made much more sense.

And now I draw my own using Notepad...

This is also the reason night-vision or night-lighting is traditonally  
red. The rods don't respond to that frequency as sharply and thus aren't  
saturated allowing you to switch from a red-illuminated scene to a  
non-illuminated scene without losing your night vision or waiting for it  
to return.

Not really, some degree of night vision is optimal for any species that  
operates in varied lighting conditions; we've just never needed to  
specialise.

No, if you loose a heart muscle cell e.g. because of an infarct it is 
lost and won't be replaced by another muscle cell but by fibrous tissue 
or fat. Though some reports exist that might indicate that sometimes

No. It's actually a photosynthetic chemical in your retina that builds 
up as long as light isn't strong enough to break it down. It's what 
microbes used before chlorophyll. It's not something in your brain.

Interesting. I didn't know what.

Does anybody know *why* normal muscle can rebuild itself, but the heart 
can't?

The fact that you don't do maintenance on your muscles and skeleton does 
not imply that it is not necessary. Some people don't maintain their 
cars and in general those cars don't live as long and healthy as other cars.

Skeletal muscle can also grow by increasing the size of the muscle cells 
(as can the heart cells). I should know if skeletal muscle cells can 
still divide in adults or not, but I don't. GIMF, but I don't feel like 
meeting a friend now, perhaps later.

I always found it fascinating how two seemingly unrelated things as how 
the eyes connect to the left and right brain and pigmentation defects go 
hand in hand. But that is as a scientist with an interest in 
development. For the person involved it is probably slightly less 
fascinating.

I think that is mainly the lack of pigment, that makes light enter the 
eye via other paths than the lens and not being able to regulate the 
amount of light. So she has to rely on slower chemical processes to 
adjust the rods and cones to the level of light.

Less serious a problem, but I always wondered how the world would look 
if it was out of focus. Whatever trick I used I was never able to not 
focus. Well, time solved this one. Now to find out how the world looks 
if you have a dominant eye. Possibly like walking with one eye closed, 
but I guess it may be subtly different.

Well, actually, the brain can grow new cells, it just doesn't do so 
much, and it wouldn't help in some cases, since the *data* is encoded 
into the existing cells. It might, in theory, repair itself with new 
tissue, but the result would tend to be a blank slate, with no means to 
relearn the correct responses. Its likely that there is some genetic 
markers that strongly inhibit new growth, precisely due to how it could 
destabilize the existing pattern.

Yeah.

As for unrivaled. In scope yes, in function.. Not so much. A lot of 
animals have recently proven to have "some" of the same key capacities 
we do, and some may even have ones we don't, but our unique mix of the 
ones we do have give us the abilities we do. Things like a single gene 
knocked out, like one group in the UK, and the capacity to form symbolic 
links in speech is greatly impaired, resulting in badly slurred speech 
and comprehension issues. A single gene whose mutant form (very few 
species, including other primates "have" a version like ours) also 
exists in parrots, who *have* the same symbolic capacity we do, while 
missing other things.

Oh, we both have found it very fascinating - her ophthalmologist took 
pictures of her eyes - most people you get a bright center (from the 
reflection off the retina), but for those with this condition, it's not 
uncommon for the iris to "leak" light and for the photo to show a "spoke" 
pattern outside the pupil area.

That could well be the case.

Pretty much, yeah.  She very occasionally will drive at night to pick our 
son up, but never on the freeway or unfamiliar roads.

>> Not to mention the nystagmus
> Wikitime

Rapid eye movement - a kind of spasm.  Essentially what it means is that 
her eyes "jump" randomly, which normally makes it difficult to read 
anything for an extended period of time.  I don't know for sure, but it's 
probably not uncommon for people who have nystagmus to be slower readers 
as a result.  My wife doesn't have that issue - she's managed to train 
herself to keep up - I don't think I've ever seen anyone read books as 
quickly as she does, and she definitely is taking in what she's reading.

Well, the thing is, even when using just one eye, if your brain has had 
practice at determining how far away stuff is, even with one eye you 
adjust and still have depth perception.  I asked my wife about this (my 
dad also had vision problems and I never understood the lack of depth 
perception) - she explained it as a calculation problem - she can tell 
how large something is compared to the surroundings, and if it's 
something she knows how large it is relative to, say, her hand, that 
helps - but her brain doesn't have enough practice at calculating the 
distance of an object moving based on those two reference points, and as 
a result, she has very poor eye-hand coordination when it comes to 
catching something thrown in her direction, because in order to figure 
out how far away something is, she actually has to think about it, while 
those who don't have the problem don't have to think about it.  According 
to her doctor, it comes back to things not being hooked up correctly 
between the optics and the brain.

Absolutely true.  The only physical activity I used to get was walking to 
the car and back and the occasional bike ride.  Started going to the gym 
about 18 months ago (Andy, keep in mind that I'm 38 this year), and I've 
had much better energy levels, been able to walk further than before, and 
overall have felt better.

I could well have continued with no physical activity, and probably would 
have been fine, but I am - without a doubt - better off now that I'm 
getting regular exercise.

You want something that's good for stress management?  Go outside and go 
for a run or a bike ride.  Or get a gym membership and go down and lift 
weights for 30 minutes.  Physical activity is a *great* way to relieve 
stress - and if you'd have told me that 2 years ago, I'd have said you 
were nuts.

Before you say "but I don't know how to lift weights", I didn't either.  
That's one of the benefits of going to a gym; you can ask people who know 
these things for help.  That's what they get paid to do.  I've worked 
with trainers a couple of times (note that this isn't a cheap thing to do 
- working with a trainer, that is - the gym membership costs us about £10/
month, and gives us access 24x7 to one location.

One important note, though - if you do start exercising, you need to be 
sure you're eating well as well.  Just like when you run out of petrol in 
the car, if you haven't taken in enough calories, you'll run out of gas.  
One thing that surprised me was that when working with a trainer, I was 
eating *5* times a day, but I was *losing* weight.  As one of my trainers 
put it to me "in order to burn fat, you've got to feed the engine".

I find it interesting that every single person's brain appears to be 
organised in roughly the same way. As in, there's a specific part of the 
brain that does function X, and it's in the same place in [almost] 
everybody's brain. Clearly much of the brain's structure must be 
hard-coded genetically or something.

Anyway, as I was saying, apparently the brain has the capacity to move 
those functions of other regions in case of damage. To an impressive 
degree...

...or again, one could argue that humans are designed for a mode of 
living which happens to involve lots of moving around. The fact that 
people need to go to the gym at all is just an artifact of our modern 
lifestyle rather than a design flaw in our body plan.

I have never actually heard that figure of speech except in the book.

I think we could arrange a provisional return. ;-)

Honestly, I've never heard anyone say it either (that I can recall), but 
these are the origins. :)

I think that also the white of the eye may transmit more.

I'd imagine that all normal depth cues (you know, the ones we use when 
composing a good POV scene) should be available to her, some less 
because of the other visual problems.

Makes sense. With the two images far away in disjoint parts of the 
visual cortex it would be hard to combine the information. Hmm, I wonder 
if the condition is more severe in man. IIRC the two halves of the brain 
do communicate more in women.

Possibly.

Oh, probably, relative size of an object to environment, shadows and such 
are all a factor in determining position; but as I said (below), 
processing that data properly is an issue.  This is why she'd never been 
good at team sports - it's hard to catch a softball if you can't tell 
where it is until after it's hit you in the head.

From the wikipedia article on OA, there are variants that affect men that 
don't affect women.

Drawing from what I heard from someone studying scattering of light in 
the eye. People with less pigment had more light coming in from all 
sides than people with more pigment. i.e. blue eyed people having more 
problems with headlight of cars approaching.

That's not what I meant. I meant that if the image of the left eye ends 
up in the right visual cortex and vice versa, you need to communicate 
between the two brain halves to match them. BTW I see now that the 
problem with the optic nerve is only mentioned somewhere low on the 
page. For some reason I remembered it as being quite common.
