I'm also well in the 30s, and I did quit my well payed job to make my dream reality. Have chosen an integrated course and I think it is quite good to have a daily class with the pressure from the instructor. On the other hand I need to deal with a crowd of younger folks (some just turned 18), but this keeps my brain competing
I found many of the replies honest and helpful. Let's go ahead ..no worries about the (our) age
