Dining with a youngish health freak recently, I was asked the inevitable question: "What's your secret for good health and mental fitness?"
This is a familiar conversation for anyone who has become a living fossil, merely by virtue of still standing vertically.
I have fielded many questions on this subject since joining the octogenarian club - particularly from anxious health nuts, all eager to know if I have some magical elixir, like carrot juice mixed with manuka honey.
I can only lamely respond, "sadly, it's all down to a steady diet of bacon and eggs, hamburgers and fries, alcohol and lots of stress that's got me through".
This, naturally, only raises smiles of disbelief.
