breaking point

I once saw a cooking show wherein the chef was giving out tips on how to cut vegetables. Interesting one is the tip he had on asparagus cutting. He says you should NEVER use a knife or kitchen scissors, but instead, you should hold the asparagus on both ends and bend, at the perfect point, optimal position, it would break--a clean break, by itself naturally.

Hmmmm. How convenient.

When do you break asparagus though? I just had some for lunch and the bunch was uncut, bundled by streaky bacon. Lunch was good.
