What about other unmeasured costs? Research shows that more than 80% of long-term prison inmates have attachment problems that stem from babyhood; there is now evidence to suggest you can predict two thirds of future chronic criminals by behaviour seen at the age of two.

Facebook Twitter Pinterest Bathers at Hampstead Ponds Hampstead Heath. Photograph: David Levene/The GuardianOn a normal sunny summer’s day there is always a nucleus of the regulars. How do they manage to spend their afternoons « cooking themselves like bits of steak, » as Professor Joad, himself a frequent visitor, teclado mecanico tfue once put it. They work at Reuters at night, or they are dentists with well-arranged surgeries, or racing car drivers. A few may be lesser novelists. Quite a lot are full-time sun-worshippers. They bring little pieces of carpet to lie on, bottles of tea and coffee and cold lunch, and evil mixtures of homemade sun lotion. Some have manuscripts. A common sight is the man who stands on his head in the corner, motionless for two hours or more – a yoga enthusiast perhaps. Another does handstands on one hand, slowly raising and lowering his body. Frequently, bodies are contorted in weird positions. This is not for the sake of any religious cult. They are tanning those last four inches of armpit to complete the overall effect.

I telephone the psychologist Cecelia De Felice. I want to know if I will go insane in my new one-woman world, especially when faced with tasks such as chopping down 27 large oaks. « You will be in a state of trauma, » she agrees. « You will quickly become lonely and paranoid. It is possible you will have a breakdown. » And if I meet other survivors? Be cautious, she advises. « They too will be lonely and paranoid. Of course you are stronger in a group. But you do not know whether they will help you or just steal your resources. Trust no one. »

The Spaniard, who will be 39 this month, is regarded as one of the most talented drivers of his generation and won his first grand prix in 2003 in Hungary. He spent 2007 at McLaren alongside Lewis Hamilton before returning to Renault in 2008. Stints with Ferrari and McLaren once more followed but with the latter’s car uncompetitive between 2015 and 2018 Alonso became weary of struggling in midfield and stepped back from F1 in 2018.

Facebook Twitter Pinterest Eduardo Chillida and Pilar Belzunce with the sculpture Lurra G98(Earth G98). Photograph: Hans SpinnerIn acquiring this land, Chillida found a home not just for his sculptures but for himself. It remains his home in more ways than one: both he and Pilar are buried on the grounds. As the title of the exhibition suggests, his message of timelessness echoes across the terrain.

Alonso would be returning without a realistic shot at the title because car development has been frozen for next year as a cost-saving measure to help F1 weather the financial downturn caused by the coronavirus outbreak. Renault are targeting a major step forward when new regulations and a budget cap are implemented for 2022.

The pond is one of the string of Hampstead Ponds forming the source of the River Fleet, which now finishes up in a culvert running into the Thames. The atmosphere of the pond and its clientele are unlike other swimming places. The local regulars are jealous of their preserves and apt to mutter on those days when a spell of good weather brings newcomers from farther afield.

« Investors are aware of negative factors, but they aren’t paying attention to those. They are looking at the Dow’s 1,000 gain, » said Norihiro Fujito, chief investment strategist at Mitsubishi UFJ Morgan Stanley Securities in Tokyo.

El Peine del Viento Facebook Twitter Pinterest Chillida’s Peine del viento at La Concha beach, San SebastiánWith this free public monument at the western tip of La Concha beach, Chillida truly made his imprint on San Sebastián. Three 11-ton steel sculptures are built into rocks jutting out of the coastline, with waves crashing against them on windy days. The work epitomises Chillida’s belief in nature’s ability to connect everyone and everything and, fittingly, a stream of water is said to flow from this part of the coast all the way inland to Chillida Leku.

In the two enclosures nude sunbathing has always been allowed, but a little while ago an over-zealous head keeper demanded that bodies be decently attired, even when exposed. The regulars kept a costume handy, ready to whip on whenever he appeared. Feeling ran so high for a while that one Sunday a demonstration against clothed sunbathing was staged, and anyone passing would have seen a succession of fully dressed protesters diving in off the top board.
