I've had long hair (down between my shoulder blades).
I can only say this. short hair pwns long hair in every way EXCEPT headbanging.
But then, back when I had my hair long, I loved it. My girlfriend at that time made me cut it off though, as she complained to suffocate from them when we were... erm... well, ya know... as they hung into her face.
But after I cut them off, there were several advantages:
-no coughing and gagging GF in bed, thus more "lub"
-better brain ventilation in summer, read less heat.
-no more painfull combing
-you only have to wash them half as much (never used conditioner though... that's just not manly)
-no more two hours needed to dry the hair (when I use a hairdryer instead of letting it dry by itself, I too get an afro-like hairstlye due to my thick hair, no matter how long they are)
-no more bundles of hair blocking drains
-no more waking up because you ripped some of your hair as you turned in sleep while lying on them
-after going out, it doesn't tangle in your face soaked with the nightly stenches of smoke, booze and vomit (without you to actually smoke, drink or vomit, your hair still stinks if you go somewhere where one or all of these things are done)
-no more pakistani rose vendors coming at you when you're out with male pals and sitting with your back towards the entrance.
