My plan to learn to play the cello (大提琴) was a health y choice. So I took the next innocent step of going to a shop that sells and rents string instruments, especially violins, violas, and cellos. The place was a hole-in-the-wall, up a steep flight of stairs. Instruments left a narrow path to the counter where a woman with grey hair and warm eyes greeted me. Since I couldn't form a question about what I wanted, I just stood there exploring the scene, which felt immensely pleasurable.

I rented a cello, a bow, and a case to hold them. What attracted me to the cello was its enormous size and its soft, smooth, and memorable sounds. It's an instrument made of beautifully polished wood that I could wrap my arms around and feel its powerful vibrations when the strings were played. That was a good starting point for me. The only problem was that I didn't know how to play it.

There's a popular belief that the cello is a particularly difficult instrument to learn. Another is theadmonition, "Don't bother if you are a beginner over age 10!" Well, I was 70, and what others thought no longer influenced me. And besides, I thought of the words of Dr. Cohen, who suggested that learning causes physical changes in the brain.

So I found a teacher who had respect for older adult beginners and I practiced diligently, daily for years, and sometimes disheartened, but I kept up. I'm happy to report that now, more than a decade later, I can hold my own in a string trio and two quartets （two violins, a viola, and me, the female cello）and even a senior community band. Of course, I'll never sound like Yo-Yo Ma but you could recognize a Mozart piece if you heard me play it. And, more importantly, I don't need to please anyone but myself.

Whether it's a pleasurable pastime or a new career, the starting point is the same: wonder, curiosity, determination, and the desire to keep your brain sharp.
