I found these riddles , can anyone help me figure it out?

[Maikadilwen]

I have many fingers,
but no hands,
I go across the world,
to foregin lands,
yet do I not walk not run not fly,
I can be short and I can be high,
in many ways i help thee,
yet do you kill me,
what am I?

Time? Probably not, but what the heck. It's worth a try.

By the way:

And, yes, he is.

That would be: SHE is. [img]smilies/wink.gif[/img]
