Matthew Walker’s TED presentation –  Sleep is your superpower  – is a masterclass in gesturing and speaking. In ‘owning’ the physical space.

Below is my analysis of Walker’s non-verbal communication at various time points in the presentation:

Start > 2:00 minute point

– If you imagine a semi-circular space in-front and at the sides of Walker’s body, you’ll observe him making measured, definite gestures and hand movements within that metaphorical space.
