#2Imo the title here buries the lede: we've known that trees form tension wood in response to external stress. This study claims to find that trees will form it in response only to their own curvature, independent of external factors even including gravity. They compare it to proprioception. That's neat!

I thought ‘interoception’ might also be appropriate in this context.

#5Trees "calculate" which branches to drop based on data they gather as they grow. A competent and experienced arborist knows how to read the tree and simply safely cut off the branches that the tree was already intending to drop so that it doesn't fall on your house or whatever. Inexperienced arborists often ignore this key dendrology fact and may totally butcher your tree. In the process they can create an even larger risk of a tree falling over onto your house during a storm
It's called cladoptosis (basically self-pruning) https://en.wikipedia.org/wiki/Cladoptosis
EDIT: since I'm on the topic of bad tree trimming, NEVER TOP YOUR TREES https://www.arborday.org/tree-resources/dont-top-trees

Or: drink when you feel thirsty and change your position when your back gets tired.

Yes, the science has moved to "drink when you're thirsty" a long time ago and it's annoying how many people believe drinking 3 liters of water per day is a key tenant of human health.
(most of) Our bodies are quite good at telling us when we should drink more water. You should never be forcing yourself to drink

All that being said, I'm not sure GP was necessarily endorsing the idea that you should drink a certain amount of water a day. I read it as a suggestion to pull away from the screen and listen to your body
