Yes I think it may be some tactile thing to keep him comfortable, like on Maid in Manhattan, the guy told the kid he held paperclips while giving speeches.Everyone has their own way of public speaking and presentation, I'm sure this is not a habit he emulates in his day-to-day. It's probably just the "style" he's grown to be comfortable with.
It is completely plausible though that he and rest of the executives have used body coaches, but like another user pointed out above, he's been doing the same thing more or less for quite some time already.
Come on, give the guy a freakin break, if that’s all you have to worry about in life, you are blessed! I think you should find out why this bothers YOU so much!As I said, it used to be fine. A bit strange perhaps for English viewers, but he just did it now and again and was barely noticeable.
This hand now turned into he constantly doing it as it's he simply can't stop himself.
It's as if he simply does not know what to do with his hands, and he's developed this habit that's gone too far.
Unless, as I say it's some body language coach who thought it looked cool, and is simply telling him to do it all the time now as they think the audience love it.
I'm now finding it really distracting as I'm watching his weird hand movements and taking my focus away from what's being said.
Wonder if he is naturally awkward without practice on a presentation, and it is a comfort thing. Because I am like that.
Maybe he's praying not to wet his pants when farting?
