This was my favourite sentence from the article about deliberately scaring ourselves:

"This recalibration account appeared to be supported by the readings of the participants’ brain activity, which were dialled down after the horror experience, similar to the documented effects of mindfulness meditation on brain activity."

I feel like that has really validated my preference for watching horror films over worthy self-improvement exercises! ;-)

The 'working out sex' one just shows that horrible 'oath' page that is now plastered over so many sites!

Designing houses around trees

Very pretty, and better than just chopping them down, but most trees that are enclosed like this will die.

There's a shopping development near me that was designed around a beautiful giant oak, and it was done as a real centrepiece. People objected in advance (including me - I was also interested because my pension fund was stumping up the funding) that it would probably kill the tree, but they said they'd had other advice, and it was sort-of open at one side, and did it anyway. The tree died, and now there's a pointless circular outsidey bit in the middle of it that they can't quite work out what to do with.

Well, drat. It makes me feel good to look at, and now I want one - but I don't want to kill the tree to get one. Is it because of lack of water and nutrients under the usual canopy spread? Or does the weight of the building compress the soil and suffocate the roots? What happens?

One issue that occurs to me is that roots are like animals: they don't photosynthesise, they respire, turning oxygen into CO2. I wouldn't have expected the roots to die of suffocation due to not enough oxygen, but thought sealing the ground around the tree may stop the roots getting rid of CO2, and result in the soil becoming fatally acidic.

However, a quick look at the internet suggests the experts really do identify oxygen and lack of moisture as the two threats to covering tree roots, even from as little as two feet of extra soil above what the tree had grown towards.
