Reminds me of the hippocampus size study from 2006 for people who do repetitive work (bus driving) and people who have to analyze roads for best paths for a living (taxi drivers) in London https://www.ncbi.nlm.nih.gov/pubmed/17024677 https://www.ncbi.nlm.nih.gov/pubmed/17024677 And from a personal anecdote, learning something new doesn't always feel like a drug or good food. News has always something new and it doesn't feel that great to consume. Learning something new that is applicable feels empowering, sometimes almost to the point of excitement and joy.
