Coffee and no breakfast - heigh, volume and temperature scales

Just some thought I had while reading stuff on the internet during my breakfast coffee.

0:00 Intro Kelvin and Celsius
3:00 A dozen
5:40 Recap of my point
6:27 A litre of cola, liquid measure
8:50 Temperature then
9:30 Special scales
10:35 I suggest a new height scale

Heights
3 SDs, median woman, 2 SDs, median man, 3 SDs.

I noticed that my audio had an annoying hummmmmmmm.
