I'm 48. I don't think it's so very old, although my children will have their own opinions.
I am, however, becoming used to the sons of former footballers forging careers of their own - Frank Lampard the obvious example.
What I wasn't ready for was the sight of Motherwell's Tom Hateley receiving the man-of-the-match award at the end of Saturday's 0-0 draw with Rangers.
Tom is son of former Rangers and AC Milan (among others) striker Mark Hateley and the grandson of ex-Liverpool and Coventry forward Tony Hateley - who I recall being one of the prized, rare cards in our playground swop sessions (you could exchange two Jeff Astles and any number of Joe Kirkups for a Tony Hateley).
Suddenly I felt very old indeed.
