I'm Tom Kubarych, a.k.a. Tombo Baggins - can you guess my favorite book?  I am a retired research scientist in the areas of psychometrics, psychiatric and behavioral genetics and personality psychology.  I know from some of the research I was involved in that you can protect yourself against cognitive aging and decline by continuing to learn new things as you age.   I started with the bass because I thought it would be easier, but it's. also bigger and heavier and I wound up in physical therapy with a shoulder injury and back pain.  I have not had any injuries since switching to guitar a year ir is ago.  Looking forward to Guitar Tricks lessons.  I have mostly been playing classic rock, with Christmas carols thrown in during the season.
