We know today’s analogy: Obsession with the body results in a small mind (and other things!). Based on this assumption it explains the phenomenon of “stupid sports people”. It is also a bastardisation of the original ideal at the origin of Western civilisation: healthy body and mind: the ancient Greeks believed passionately about this and many of their first philosophers were fit and active in body as well as in mind. But this process didn’t arrive at once, the faculties of the mind and body have to be nurtured and developed, body first, as that supports the brain, then, with sufficient physical development, the mind. Many of the ancient philosophers lived to old age, which, considering the times they were in and the equivalent state of technology they had, was a great testament to their 'healthy body and mind' lifestyles. Of course, the philosophy we know of theirs today was mostly recorded in their older years, and this is due to the natural progression of life, not by premeditation on their behalf.
