When the New Zealand Woman's Weekly recently suggested that I might be Australasia's oldest new dad, I immediately panicked, mumbling "this can't be true" as I turned to the internet.
I found it beyond belief that somewhere out there - west of Alice Springs, maybe - there wasn't a wizened-up old crock with more time on his hands than me, still producing children. Alas, none.
I then searched other sites, starting with my birth country, England, only to discover that there, too, I was embarrassingly up there in the ancient father stakes.
Spookily, I read an account about Britain's oldest in the Guardian which introduces the story with a telling line. 'There's something about Lincolnshire: its cosy backwaters, fresh air and abundant vegetables - and now the emergence of Britain's two oldest new fathers within a week."
The two Lincolnshire lads are mere chickens compared with me, only cracking 74. However, I found myself nervously whispering to the caregiver: "My family are from Lincolnshire too - do you think there's something in the water I don't know about?"
