Climbing up the fretboard is much safer; if you lose your grip, all that can be smashed is your reputation. I think Will will come to grips.

Bruce's version says "On his tombstone bears this scrawl ...", which opens a new line of thought: Are the bears condescending, because they can climb higher than flies but know their limits?

I would have scrawled: If you can fly, don't bear the risk of climbing.
