Ear wiggles, tides, cracking joints

Dr Karl Podcast

About this episode

Is there a difference between a raised heart rate from an energy drink compared to excercise? If we didn't have high tides or low tides, what effect would that have on Earth? Why can some people wiggle their ears without touching them?

Dr Karl answers these questions and more on triple j Mornings with Lucy Smith.
