Mental powers start to dwindle at 27 after peaking at 22, marking the start of old age, US research suggests.
Start of old age? Thank you very much.
Seriously though, the article does indicate the need for more urgent research, citing the current incurability of dementia and Alzheimer’s.
Over the past 18 months I have been reading up in my personal time on water, its availability, requirements, usage and distribution. I believe it to be a particularly important problem for systems engineers to examine, since it needs to combine aspects of purification technology with energy analysis, human practices, policy and politics, and one which I believe mainstream media does not report on as much as it perhaps should.
I was therefore happy to read a well-written BBC article by Richard Black that describes the problem and complexity of modeling water as a resource. If you’ve been trained in chemical engineering or systems engineering, the material is probably not new to you, but it’s presented very well.
