Another maginificent show, I loved the mix of sciences covered - something for everyone. The cryptic subject titles raising the anticipation trying to imagine what would be covered. I was delightfully suprised when the speed of death wasn't what I had thought it related to which involves outwalking the grim reaper from a study at a Sydney hospital. https://www.bmj.com/press-releases/2011/12/15/outwit-grim-reaper-walking-faster

Also the whip bird call is very distinct, https://www.youtube.com/watch?v=N-YtkmwlTZ0 but I know have the opeening song from the 1968-1970 TV series Skippy the Bush Kangaroo as I think its the Whip Bird's call that Sonny used to call skip at the start of the song. https://www.youtube.com/watch?v=_agtNKbgSfI

Now back to counting SETIs.
