I have a lot of elderly friends, from folk music jams. They’re in their 60-80 phase, plenty of money and energy, decent health, minds still in tact. They’re learning new tunes, arresting the decline of technique, interacting in person regularly with others. If every older person did this, their minds would stay a lot sharper for longer. Every day you’re minutely deliberately improving and learning new tunes.

Grab a bodhran or banjo and head to a local folk jam everyone!
