Now, ... going back to the yahoo article citing the 19-year age gap between a Glasgow couple:

Let me tell you about my late wife's brother, Robin (Bob) and his wife, Linda ... who met in 1967, when Bob, an Architect, was already 35 and Linda - his Office Junior - sweet 17. They married the following year ... and will celebrate 44 years of marriage a week today. Come July, she'll be 62 ... then, in September, he will turn 80.

Quite a remarkable achievement - by ANY standards - let alone for a British couple.
