Preparing for another overseas journey, I've been experiencing the usual onslaught of pre-flight nicks to my credit cards.
The first nick was for a compulsory medical certificate from my GP, confirming that I'm still standing vertically and should be able to handle two weeks in foreign places, covered by expensive medical insurance.
This is the penalty for being an octogenarian. Once you hit 80 it's all uphill - the insurance industry is clearly pessimistic about my ability to return in one piece.
The third nick is renewing a visa entry to the US.
As well as having to pay, the US authorities require me to supply details of my mother's maiden name, which is apparently now regarded as indispensable information if you're planning a stopover in the land of the free.
