For some individuals Age actually has a lot to do with it. If one is fortunate enough to live past the average age before dying, they may have to deal with mental issues such as memory, recall and cognition. Without these it is nearly possible to learn new complicated ideas then recall them to put to use

Age has nothing to do with it. It all about personal interest and the willingness to spend the time needed to master the software of choice. Plenty of people half you age and younger have no more desire to invest their time learning new software then you do.
