Stephen Hawking:
As a small boy, I used
to take things apart.
I wanted to find
out how they work.
That is still what I want.
But I have moved on
to bigger things...
like the universe.
The thrill of discovering
something no one knew before
is like nothing else I know.
I want to share my
excitement with everyone.
My main challenge has been
Lou Gehrig's disease, or ALS.
I have had it since I was 21,
but it has not prevented me from
exploring the universe
with my mind or having
three wonderful children.
