I still stand by my wisdom/experience equation as the wisdom would come from the individual asking the advice from untainted source....However if i was maybe to be devils advocate against my own theory i would break the wisdom age ratio down like this according to personal self knowledge.....
Ages 50-90 years old = Top of the tree wisdom. Youve lived,loved, lost etc etc, although you can be let down by saying things like "things were better in the old days". (things actually were better in the old days IMO),
Ages 40-50 years old = True wisdom is slowly coming into bloom and the realisation that the only knowledge you really have is that you don't have a clue and that you are more or less as much of an ignorant twat as everyone else on the planet. Very enjoyable.
Ages 30-40 years old= The salad years. You are both wise and ignorant in equal measures.
Ages 20-30 years old= The idiot years. You think that because you are no longer a teenager, you know it all and continually spout unsage advice to anyone that will listen. Probably the low point in the passage to pure wisdom.
Ages 10-20 years old= The experimental years where the roots of wisdom are laid. These years and the 20 something years are when important mistakes are made in order for us to learn from,,,, eg don't get drunk and take 4 white lightning blotters 15 minutes after each other because you dont think they are working. Patience young padawan.
Ages 0-10 years old=The purity of ignorance. Beautiful innocence. God bless the children.
