Zero is a natural number according to some people such
as Eric Hehner from the University of Toronto. The following
is what he said in one of his books:

"Your life begins at year 0, a highway begins at mile 0,
and so on."

If we treat the number zero differently, things can get
unnecessarily complicated. For example, if people
used the number zero like the way they use other numbers,
we wouldn't have something like "unchanged" or "<= =>"
in the stock market report.

As I understand, the definition as to whether or not
zero is a natural number is not universal. Personally,
I consider zero as a natural number.
