No, I'm currently 63. I started bonsai when I was 16 or 17. I don't remember exactly when, but it was soon after I got my driver's license because I remember it felt strange to drive to see Brother Paul at the Monastary in Conyers!@AdairM I thought somehow you were only in your 40's?
I did take a break from bonsai for a while after my ex-wife killed all my trees. When I returned to bonsai I decided to specialize in JBP, and only work on "good" material. So, now about half of my trees are JBP, the rest are other Pines and conifers. Except the Shohin! You have to have a variety of species to make a decent Shohin display.
