@Tomalak : just because something is put on screen doesn't make it canon if it's totally illogical, stupid and out of character. And just throwing a line about Data aging without his body being greatly modified is completely illogical. But I guess that's an endless debate...
It's not really a debate, it's just the reality. There are plenty of illogical, stupid and out of character things within the Trek canon. If it's on screen, it's canon.
