Babies See Robots as Sentient or Inanimate Objects

This tells you, that in our future, people will relate to robots and probably other objects with applications, as if they were human. We will have feelings for them.

Twins Will Orbit Together

Interesting article.
One thing at the end struck me.
My brother and I also don't shake hands.
I guess, to us it has never been necessary.
We live in parallel, in constant contact thru
the twins string. I think it is a twins thing.

Identical Twins Not So Identical

My twin brother and I are clones. However, there have to be
some differences. Over time and because of our different experience
we are not exactly identical anymore. Life has a tendancy to skew
us in many subtle ways.

I think it's amazing the things kids laugh at.

Why Are Identical Twins Different

My clone and I are different in experience mostly.
We have lived in different places for more than half
our lives. We have different experiences that have skewed
our visions of what the world is around us. However, we
we have come to so many parallel conclusions in our
decisions, about direction and things we learn from life.
I think a lot of who we are is about genetics, how we were
raised, who our peers were growing up etc....
We are still more alike than not.
But you have to keep in mind that we are individual souls
in geneticly duplicate bodies. For whatever reason that
you can imagine, we decided to come into this life together.
