Introducing our first "Shorteas" episode - one where you can take a quick time out of your life, to receive a tune up, or an infusion of information or just have a good old giggle. Today we have all three as Keith and Nikki are back in the deep blue ocean to figure out why whales sing.  There are are more reasons than you think, and as always they throw in some extra bonus facts to flex the mind.  The cool part of this podcast is that you are going to feel like you're in the deep blue ocean face to face with these gentle giants. We will be transporting you there through their melodious singing. So pour yourself a cuppa, or just close your eyes and relax while the high frequency whales sing their magical songs . . .
