He who does not have a good head on their shoulders better have a good pair of legs

My parents, immigrants to this country from Europe, would say the following phrase.
"He who does not have a good head on their shoulders better have a good pair of legs, because they are going to do alot of walking."
What country did this originate from? Is it Greek? Swedish? or from somewhere else?

This is interesting. I'm Korean and here we have a saying goes like, "If someone has a dull brain, it's his body who suffers from it'.
Clumsy translation, but you can guess the meaning I hope? If someone's not very intelligent then they probably will end up doing things in more inefficient way, causing more physical work and time, effort. So I guess, what you asked about has somewhat similar meaning with this..'If you can't trust your brain, then at least you'll have to have a strong body'

Una.
