Pauses are better than ummms

Who would you rather be, Boris Johnson or Barrack Obama?

A Boris Johnson answer is full of posh sounding filler noises.

Obama pauses, and comes across 10x smarter.

(It helps that he probably is 10x smarter.)

But, umm using less, like, umms, arrrs, and likes, makes you, y’know, sound more confident and in control. Plus no-one wants to sound like Boris.
