Ever wondered what really differentiates a man from a woman?

Some of the very first objects or aspects that come to mind include:

1. Differences in voice pitch between males and females with females having high pitch voices naturally with respect to men having baritones.
2. Differences in shape physiologically speaking, with ladies having the necessary curves, endowments and bends in all the right places yielding the typical figure 8 as we call it, as against men being straight... I am sure you know what I mean. Sorry, I did not say figure 1!
3. Tiny frontal dots on the chests for men and large shapely and of course succulent ripe melons for the ladies (Did you say boobs?).
4. And that tiny waist, of course that goes for the ladies, not the macho 6 packs for the men.
5. And so much more...

The list is virtually endless.

However, surprisingly, one is shocked to find that in spite of all this differences (and natural demarcations) the female Instruments often steals much of the properties of male Instruments.
You could almost mistake one for the other in this typical example here: http://www.nudeerotics.com/this-is-africa-me-2/

No wonder she is called wo-MAN!
