My brother is 46, has an MBA from UCLA, business owner, doesn't need to work for anybody else for the rest of his life, grown up kids, etc. He started with typing classes ages ago, went through the motions with MS Office tutorials .. and now he is somewhere taking advanced Excel scripting, really funky stuff involving ODBC connections and ETL. He is just one of those people who never stopped going to night schools and now he is very sophisticated.

I would say go for it.
