They say that, as you get older, your ability to absorb new information diminishes and your capacity to hold old information dwindles.

In the same article, I promised a follow on in my next missive on the subject of outreach in schools, whose pupils are the biggest absorbers of information and ideas. Although many of us focus on university students in our teaching, we should remember that no age is too young to start a noble education in ocean science.
