Okay, sorry. I should have picked up on that.

Regardless, even if you don't care about or agree with that definition, your mere assessment of it as the most reasonable is subjective and arbitrary. It's just what "seems right" (or seems reasonable I guess) to you personally. I'm sure you realize that... my point is, there's no escaping this sort of arbitrariness when it comes to placing the "bright line". Hence the rightness of atmosfear's comment that the line's placement is culturally rather than medically or biologically determined.
