How to measure human sensitivity?

Women accuse men of being "insensitive", while men blame women for their "over-sensitivity". Really, how does one measure sensitivity? This epic emotional battle between men and women has been in existence since time immemorial, or atleast since Adam and Eve, whichever came later. Yes, it is an exciting question to ask, the question of "why do you say 'whichever came later'. I do have my theories to back it up, but that would just make me digress from the issue at hand.

The issue is, how does one measure sensitivity? Without a decent measurement tool, how can anyone accuse anyone else of being "less" or "more" sensitive --- less or more than what? Ah, probably it is just something that is measurable by common-sense. But as is commonly said these days, common sense is no longer so common.

Being sensitive makes one get hurt more often, while oneself hurting others not so often. Being insensitive is like emotional blindness, one doesnt see that another is hurt due to one's actions and thus is very much like an armour against the world. So, is it better to be insensitive in this cruel world?

If the world were devoid of sensitivity, maybe the world would be simpler like the men imagine. Or it maybe a much colder place like the women fear. So we (women) tie up our shoelaces and keep marching on into the sensitivity territory, where no man has gone before (pun intended), believing all the while that the men will catch on soon enough.

Given a choice, I would prefer over-sensitivity to insensitivity. After all, "over-sensitivity" may even be tamed down a bit but "insensitivity" could never be replaced by its opposite.
