Even today, 20 years after my childhood diagnosis of attention deficit hyperactivity disorder (ADHD), I am still keenly aware of how my attention wavers, lapses or holds differently from that of most people.

Sexual activity linked to higher cognitive function in older age

A joint study by two England universities explores the link between sex and cognitive function with some surprising differences in male and female outcomes in old age.

  • A joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher cognitive abilities in older age.
  • The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
  • The differences in testosterone (the male sex hormone) and oxytocin (a predominantly female hormone) may factor into why the male cognitive level changes much more during sexual activity in older age.

  • We used to retain reams of valuable information; now we're more likely to memorize URLs and passwords.
  • The process of deep learning is being sacrificed to our addiction to novelty.

It really is more difficult to learn a new language when you're older. Here's why...

It may be easiest when you're young, but the proven benefits of learning a new language at any age cannot be ignored.

  • We have two main memory systems that influence learning: declarative memory, which consists of facts that can be consciously recalled, and procedural memory, which consists of different "procedures" we learn that are more instinctual to recall.
  • Young children are able to access their procedural memory systems without the distraction of a declarative memory system. That means they can pick up grammar and language faster.
  • There are many ways you can make it easier to learn a second or third language as an adult, and there are many benefits to doing so.
