Maybe not quite that many, but I have many-a-time blogged about the sudden acquisition of a basic and somehow overlooked piece of fundamental logic.
I was reading about trees recently - deciduous varieties - and it seems that at the point that the tree decides, through chill or lack of light or combination of both that it is time to let its summer coat go, a chemical reaction takes place and each leaf detaches from the mother ship, deprived of its usual water and nutrient supply.
Every species of tree is different of course - early budding and early shutting down such as the horse chestnut, or more cautious, like our very late-leafing apple tree which still seems to have ninety percent of all its foliage. At the moment our lawn is perpetually covered with papery yellow and brown leaves of our towering lime tree.
Usually, we rake, perhaps dump the leaves on a tarp and drag them to various mulch piles, the tarps gradually ripping and thinning in the process, or just pick them up by hand. But this year, Dr Lockett seized with sudden wisdom, cut two pieces of old hardboard from the woodpile and started to use them like large mole hands. It's transformed the job, the leaves crushed and pinned between the wood - actually very satisfying to do too. Why did we not invent this before?
