I would like to know where you saw/got that?
I actually wrote....my own personal feeling is that his stripes won't grey out. But will I advertise him as not going to grey? Absolutely not.
Please don't put words in my mouth.
The bottom line is that neither you nor anyone else can prove for 100% that he will or will not grey...as it has always been the case.
It will be a wait and see thing...as always...
