generally age = experience, but youth does not necessary equate to inexperience. the way i look at it is, the experiences we have will fall into different categories:
General experience
nearly everyone will have these, but they come at different stages in your life.
Personal experience
an experience you get that not everyone can relate to, the chance given to you by your choice of profession and what not. Essentially these experiences come from choices rather than age.
Random Experience:
i look at this one for people that just happened to experience fame or an experience not many people have experienced, and you would be lucky to have experienced these.
In this example, older people will have more general experience, while anyone could have more a personal or a random experience. You could prolly wright this better with more specific and more of the different categories of experience, but yeah.
