infinite loop using string and size_t

Hey guys,

why does the following get me an infinite loop?

Code:

---

for (size_t i = myString.length() - 2; i >= 0; --i) {
    cout << "test" << endl;
}

---

size_t should be able to take the value of 0, so what seems to be the problem here?

size_t is unsigned, so >= 0 is always TRUE.

Damn, how stupid was THAT?

Thanks.
