Common sense is not common

Once I discovered "Common sense is not common any more...."

It turns to be odd, irrational and uncommon. What does it mean?
The world is built on illusion, lies and misfocus-values...., I think.
What can you do?
To uncover the veil? To preserve the current status? To....
Who knows?

We sometimes say gut feelings, or intuitive ability, or conscience.
But in fact they are no more common too,
mixing up with many different ingredients therein.
They are losing somewhere here or there,
in the corner where one never aware.
Though we still can hear of them, sometimes, in words.

Please please don't just put them in words, but in reality!!!
