Is it not a natural now that he is turning 72?
Considering how he is been on so many on other topical GD things, surprised that this hasn't been mentioned.
Of course, it's natural. One factor is that Phil, relatively speaking looks young for a 72 yr. old. He doesn't act or look 9as far as we know) like a typical 5o yers old.
Hell, I'm 50, but usually am mistalen for someone much younger. On the rare occasions that I go to reunions and such, I'm a bit distressed about how many of the beautiful women have "old lady" hairstyles now.
