Maybe people increasingly don't wear ties because they don't know how to tie them.
I know how; it's just a silly, fatuous, futile, pointless thing, that's all.
Just like religion.
Oh: did I mention religion? Oops.
But anyway: ties are the same. Occasionally decorative but basically useless. I know how to tie the basic four-in-hand, Windsor knot and proper/real i.e. non-elastic bow tie too, but that's purely for my own transitory gratification.
Which is to say, looks smart for a brief function, but that's all.
I.e. religion again
