Recently I started doing a music healing group that meets every Saturday for two hours. The group is free so there has been a flood of interested folks. One of the things that I have noticed both in my new group and in concert audience populations at large is that people of all ages love music and an participate in musicmaking their entire lives. Years ago it was pointed out to me that orchestra conductors frequently live into their 80's and 90's and many conert pianists were concertizing well into their 80's. I heard Artur Rubenstein play a fabulous concert in Italy back in 174 when he was 88 andit was as beautiful a recital--and grueling-as I've ever heard.
Personally I choose to believe that staying active in music-making and music listening will keep you yong for your entire life! It's worth a try isn't it?
