Does age play a role in the way we write ? In other words does youth and old age contrast the way we write?
I would say so. People get more experienced as they get older. Also, growing up in different generations could alter someone's style of writing from someone else's who is much younger/older then them.
Any two writers differ in their work. But what's more interesting, if you compare the sape person in younger or older days, you can usully feel different about her writing. People change all the time and their writing shows different sets of words, different ideas, differnt language.
