You're agreeing with me.I suspect things I learned when I was 19 like physics, chemistry, and mathematics will still be applicable for a few more years.
But then again.... what are the chances?
Big difference between things you learned and things you trained for. Physics, chemistry and math are not vocations. They are foundational knowledge that allows you to be flexible and adaptable, by giving you an understanding of the world around you and a general ability to manage large amounts of information and make sense of it. Just like the ability to clearly articulate your thoughts (Linguistics and Literature), make well-reasoned arguments (Philosophy), put real-world situations into context (Anthropology, Politics, History), and reach others on an emotional level (the Arts).
