I am using your "advice for young people" in my chemistry class to close out on Fridays.  What an awesome question to ask, and what wonderful insight by top minds that is provided to our new generation of scientific thinkers.  THANK YOU FOR TIME-STAMPING LEX!!!! I am going to request a 10 minute talk as a guest speaker in my course, but understand this is a very tall ask.....  This podcast is the best on YouTube, BAR NONE!
