As a tangent to "...I am sometimes surprised that the guru I have been working with is only 17 years old."

I am frequently astonished that the 17 year-old (or more ...or less) guru deigns to help me; nay, even consents to discussion, as my antiquity (64) and sparse knowledge are so often read as "next to dead(brained)."

Thanks, Monks. you teach well and generously.
