It makes perfect sense to me. Proficiency can lead to complacency.
You become so good that you forget the inherent risks involved.
Just when you're not paying attention, you get bitten.

Similar idea to an experienced carpenter losing a finger. They
use the power saw so much that they forget how quickly it can do
damage.

Every close call I've had was due to minor inattention.

Martin,

This makes no sense. I believe that the more you do
something the more in practice you become and the inherent
result is that you are safer. Complacency is not an
argument against doing something!
