I love carrying stuff on my head. It's so much more comfortable than carrying things in my arms! I don't have the balance to just carry it "cold" though - I have to put a hand up for support. (I think when people in other cultures carry stuff on their head, they wrap a piece of cloth around their heads to create a larger platform, don't they?)

As far as squatting on my haunches - it's the flexibility in my Achilles that I lack. Since you're bent at the hips, you're not really stretching the quads. I'll do it, but generally I have to put one knee down and shift side to side.

Don't most American women crouch over public toilet seats? As far as aiming, that's kind of a pet peeve of mine, and not the way you'd think. Women have the physiological ability to pee standing up and aim accurately the same as men, it's just that our culture (and most world cultures) doesn't allow girls to learn to touch ourselves "down there" when we're of an age for toilet training. By the time I learned (in adulthood) that it's possible for me to pee standing up, I just don't have the patience to toilet train myself all over again - even in the shower where I won't have to clean up after my feeble attempts. I don't have kids, but it takes, what, months to a couple of years of every single urination for a little boy to learn to aim? I tried, I gave up.
