Well I'm an engineer and like Andres I think that science is a "fascinating seek for the truth".

I know that what my friend does cannot be explained by Newtonian Physics or even Dimensional Analysis. So it can't happen!!! But I've seen it enough times to know that it DOES happen.

She can take someone's hand and look at it a while and say something about that person that is unusual enough that it is beyond the realm of a reasonable guess.

For example she was talking to one guy - he was a salesman that she had never met before. She looked at his hand and said one thing "You used to be a singer".
Now that phrasing stuck me as really strange immediately, because I'm a singer and I don't know of any singer who would accept the phrase "used to be". We are singers or we are not singers and "used to be" doesn't come into it. Except for this guy, his eyes opend wide and he said "Yes, I used to sing in a choir". Now for some reason or other he had stopped singing and he didn't consider himself a singer any more.
