[quote me] The bigger they are...

...the heavier they get.

I say this because I have observed that confidence and body width-to-height ratio are somewhat proportional.  It was true to me, too - I became a more confident person at about the same time when my BMI was starting to knock at the doors of 25, i.e. the overweight door to obesity.

It is so true as well in public transportation systems.  I've seen large width-to-height guys occupying a wider portion of the seats in buses and so on, and yet they still have to stretch their thighs outward so they occupy even more space.  Is it because they don't want people near them because they know they smell?  Or have they just overtaken their self-confidence to the point of rudeness?  What's up with that!

But then, is society to blame as well?  Can you imagine a large guy who's as shy and as soft-hearted as a smaller, thinner man?  Weird, isn't it?  Are these XXXL guys just living up to the hype?  Or did the David and Goliath story created a reverse psychology effect on us?

Last point.  East Asians and Southeast Asians are generally shorter and thinner.  Caucasians are generally not.
