73...As we age our brain continues to process music even if suffering from advanced forms of functional brain diseases. Altzhiemer's studies show the hearing centers in the brain are the last to go! So if your ears work you may find, as I have, when your knees, and eyes, and lower back give out, as they will without exception if you live long and whether you prosper or not... I can still get a platter on the turntable or a disc in the CD or tune-in public radio stations for symphonies, jazz and blues...and make it back to my chair. Where is that Beefheart album? Turn it up.
