Recognised as one of Australia’s most trustworthy people, Dr Karl Krszelnicki has just released his 44th book, Vital Science. As his brilliant mind does, Dr Karl answers the questions you may not have ever thought to ask! Is cockroach milk really the next Superfood? Why are birds so smart? How long does a decapitated head stay “alive”?

With the release of Vital Science, author, medical doctor, engineer, and physicist Dr Karl sat down with (Dr) Joel Cassim to give us a little insight into how he gets the knowledge to continue to bring us wonderful books, and answers the age old question: What is Karl’s favourite milkshake?!
