My dad is still among us, even though I grew up with his take on it, loosely translated:

Early awake, early asleep. That brings health to every weeb.

It's possible that he already translated it from English (your dad's saying or an unknown variation of it), and that I've now translated it back to English, for each translation moving a bit further away from the original meaning in order to keep it rhyming. (I wrote "weeb" to make it rhyme, my dad's version said "boy".)
