Rog L, my opinion:
When people stop learning, they on their way out of this world. I have an IPad, two computers, three keyboards, and lots of guitars. My day is filled with learning and excitement. My 91 year old guitar playing friend and I share something precious; we are never bored. Never stop living and learning. Sitting around a table talking small talk that goes nowhere is a no, no for us.
My 81 year old sax playing friend found that he cannot play his sax more than 15 minutes without tiring – so no more gigs. But—he is now collecting recorded music and putting them on CDs – he is preparing to be a DJ. He may never get there but so what; he is not bored, and he still filled with life.
