My parents were great musicians - my mum a cellist and pianist, my dad played clarinet and saxophone. Both our daughters were excellent musicians too. Totally by-passed me though ... and I am very jealous of those who do play.
OH never had the chance as a kid (no money) nor as a young adult (worked VERY long hours, for many years 140hrs a week- and even at end of career, about 90). Now retired, he has taken up the accordion, has a great teacher (very pretty too, hmmm) and absolutely loves it and has made incredible progress. Anyone who learns an instrument 60+ has my total admiration. I'm sure it is great against Alzheimers too.
