> would raise the prospect of new treatments to allow older women to conceive This is a bit of ethical problem. Pregnancy at older age brings many risks to mother and child.

Yet, women who give birth later, live longer.

From your article: "The natural ability to have a child at an older age likely indicates that a woman’s reproductive system is aging slowly, and therefore so is the rest of her body."

It continues to astound me how little we actually seem to know about anatomy, especially women's anatomy (hold the jokes, folks).

What astounds me is that the human brain doesn't even know it works (at least consciously). Your brain tells your body what to do, but your consciousness has no idea how.

For me, that's what's so amazing about neural networks! If you could ask an individual neuron why their f(x) is the way it is, they probably would only be able to tell you that "that gets the result the brain wants". They're like individual computers, yet they can't work alone; only when put together does what they're doing make sense.

I wonder why we don't have several conscious thoughts at once.

What bothers me is, so many doctors and scientists saying "no" / "it doesn't happen", as opposed to "we don't know". They haven't observed it -- or, as often, been told/taught it by someone else. So, it doesn't happen -- it doesn't exist.

At this point, I feel outright lied to. I've made life decisions bases on such statements that proved to be patently false and not at all backed by real science.

And a lot more anecdote and "uninformed" practices of friends and others, that I initially avoided and regretted witnessing, based upon these "expert" opinions, has actually proven to be healthier and more productive.

I sometimes feel I do, but then my sense of introspection goes bonkers.

I have three possible theories for this:

1. Evolution saw no need for it; knowing how our eye's classify light signals into objects and figure out depth etc are not important to survival. What is important is knowing exactly if you are looking at a predator as soon as possible.

2. Too much data for consciousness to handle; There is something like 1 million connections between each eye and the brain alone. Then there is all the parallel processing that must take place to match what we are seeing to the right memory. This process reduces the all the incoming signals to a single variable such as 'car', 'red' etc which can then be passed to our simpler, serial experience of reality.

3. A bit more 'out there': The physical dimension we inhabit is the result of the intersection between two planes, time and space, that seem to stretch to infinity in both directions (no beginning and no end). You could also say this for your own thoughts; do you truly know when a thought begins, or when it ends (no longer part of the brain)? We seem to exist in the middle of these planes, and perhaps that is all that is possible for the conscious experience (meaning, being part of the process of 'seeing' is just not possible).

Perhaps we do! How do you know that your autonomic nervous system isn't consciously regulating your breathing, digestion, and heartrate, blissfully unaware of the less important unconscious processes that acquire food and move about. (I wrote a science fiction story along these lines once, that was described by readers as "uh... interesting, I guess.")
