I wonder whether you would agree with me that London mayor Boris Johnson has a tendency to be a complete lunatic at times?
The latest benign manifestation of his wackiness is the proposal that we turn our roof gardens into allotments, convert railway yards to wheat fields and plant crops in the cracks between the pavement - all in order that we have food grown in London to feed the 2012 Olympians. It makes you wonder whether Boris is aware that fruit and veg is widely available at the supermarket these days?
Two further thoughts also come to mind. The first is that surely the 2012 Olympians would prefer to have their Brussels grown on a nice farm in the country rather than on a reclaimed brown-field site contaminated with fumes and who knows what else.
The other thought is that the mayor's grow-your-own policy is just the latest example of how the Good Life approach of self-sufficiency seems to be gaining popularity in recession-hit, globally-warmed Britain.
But while it is laudable to reduce your carbon footprint, to keep food miles down to a minimum and to give the kids fresh cabbage from the garden to turn their noses up at, I can't help thinking that the dig for victory approach - all very well in the Second World War - is not necessarily an appropriate response to 21st-century world economic catastrophe.
You might think that growing your own veg will save money, but by the time you have bought the seeds and saplings, planted them, paid for tools and put in back-breaking labour (possibly leading to back-ache for which you will need time off) you will probably find that the money and time invested far outweigh the results.
You need a pretty big garden and fair amount of free time to produce enough food to feed yourself and your family. There's a technical term which covers this practice - it's called "farming". And it is best achieved on a large plot of land in a rural area, rather than on a few square yards of front lawn in NW4.
If you want to spend your time doing something which might produce a tangible boost to your income, better to go for a little mini-cabbing - it worked for a lot of people during the last downturn.
Looking at the bigger picture, there are few economists who would argue that the way to come through a credit crunch is to revert to a primitive rural economy based on barter, with a few chickens and a goat in the back garden.
And yet, who is to say that all this mechanisation and industrialisation we have seen has actually improved the quality of our lives? Surely, our ancestors lives were happier when all they had to do was concentrate on rearing a healthy brood of root vegetables.
Ah, the bliss of popping out to the garden on a Friday to pull up a few beetroot for borscht and catching your own chicken for Shabbat dinner.Imagine the pleasure to be gained from picking your own potatoes for latkes, your own fresh carrots for tsimmes and shechting, gutting, butchering and hanging one's own cow for a really good salt beef sandwich.
And the great thing is that, as we revert nostalgically to our modern version of the Pale of Settlement, there are more than enough Russians, Poles and Lithuanians in this country to make for a proper retro-pogrom.
All together now: Anatevka, Anatevka...
