Wisdom

So, wisdom.
I was wondering, what happens to truly WISE men/women? I mean, some people might argue that these wise-persons become preists or religous leaders. But seriously, other than a lot of devotion and memorizing you don't really need wisdom to be one.
If you check the dictionary it mentions that wisdom includes (as an accepted definition) the "accumulation of Philosophical or Scientific facts" but again, knowing all about philosophy doesn't make you wise necessarily. And knowing a shitload about science makes you knowledgeable, again not the tipe of WISE that makes people say: That man is a wise-man.
What do wise people do then? You won't get payed for wisdom. If your skill is to be wise, what would you do with your life?
