Unlike his only other (two) Oval Office Addresses, last night Barack Obama was standing.
With the "Resolute Desk" behind him (rather than between him and his audience), the President (or anyone) will project and feel significantly more strength and resolve while standing. And even though this was a traditional speech (written in advance and read, as opposed to a press conference or debate), standing strongly engenders greater fluidity and confidence versus saying the same things while seated.
Standing has also been shown to temporarily increase testosterone (in both males and females) while also lowering cortisol (a "stress hormone"). This effect should not be trivialized or ignored. If you want to increase your assertiveness and look as well as feel more determined - take this one standing up.
